Residential Reverse Osmosis Systems - The Hidden Dangers

It never fails to amaze me the hype surrounding these residential reverse osmosis systems. They use an outdated technology, waste an astonishing amount of water and are expensive to maintain. Let me elaborate.

osmosis water system

These systems were originally designed for industry, such as the photographic industry, which needed large quantities of mineral free water, and then because of the demand for home water treatment, went on to become hyped as state-of-the-art. These reverse osmosis systems residential water purifiers however, are simply not effective and potentially harmful.

OSMOSIS

Let me explain.

Residential reverse osmosis systems use a semi permeable membrane with a very fine pore structure, which basically stops most things from passing through, great you say, right? Well no actually, not so great.

Firstly, they remove the extremely valuable trace minerals we need to stay healthy, such as calcium and magnesium. We are designed to receive these minerals and the loss of them can lead to long term health problems.

A recent World Health Organization study concluded that our water must contain some trace minerals to promote good health, one of the hidden dangers that reverse osmosis systems residential sellers will neglect to inform you about.

Secondly, for every gallon of demineralised water they produce, around 2 -3 gallons is lost. This is just not acceptable in my view in today's environmentally conscious world. There is no new water, the planet just reuses the same water time and time again. These residential reverse osmosis systems were designed as I have said, for industry long ago when we weren't facing the problems we are now.

Thirdly and finally, reverse osmosis systems residential can require extensive and costly maintenance.

What you need is a good quality water filtration method, one that preferably utilizes a multi stage process, using an activated carbon block filter. The first stage will remove the toxins and contaminants while the second stage restores the ph balance, a very important factor to keep the water from becoming too acidic.

The very best ones will remove 99% of all the bad stuff and leave in those vital minerals, leaving you with great tasting water without the worry.

So now that you know this, keep away from those residential reverse osmosis systems, and perhaps research a little on the types I have outlined for you, to find the one that best fits your circumstances.

There is no better feeling than knowing you have great tasting, pure water and are doing your level best to protect yourself and your family.

The Pros and Cons of Reverse Osmosis Systems

Reverse osmosis systems is just one type of many water filtration systems that are available on the market today. Water filtration pushes water through a filter that traps contaminant molecules and releases pure water molecules. There are many health benefits that can be had from the use of water filtration systems including reverse osmosis systems.

osmosis jones

The first benefit is clean and safe water to drink, bathe, or cook in. Exposure to contaminants is greatly reduced or virtually eliminated. This results in fewer occurrences of diseases including cancer and skin irritations/disorders. With lead content being eliminated or reduced there will likely be many fewer occurrences of learning disabilities in children that currently occur at over 400,000 in the United States yearly. Skin and hair become softer and more properly hydrated.

OSMOSIS

Osmosis is a process whereby a solution is pushed through a semi-permeable membrane with the lesser concentrated solution moving through the membrane to the greater concentration until the solutions become equalized. Reverse osmosis is where water is pushed through a semi-permeable membrane and pressure is applied to stop osmosis and then reverse it. It is a slow process and the result is pure water. The contaminants are trapped in the membrane which is an extremely fine membrane.

The pros of using reverse osmosis systems is that pure water will result. It is a popular seller. The same health benefits mentioned previously can result from using these systems. Although slow they are effective in removing contaminants.

The cons of using these systems lie in the fact that though they remove contaminants they also remove important minerals including magnesium, calcium, potassium, and many others. Depending on need and budget these systems will still be a good option for many consumers to consider for purchase.

Reverse Osmosis Water Treatment Systems - Do They Work?

If you want to finally find out whether reverse osmosis water treatment systems can effectively purify your water at home then you'll want to read this article.

osmosis water filter

We know that drinking untreated tap water is very unhealthy, with all of the weed killers, pesticides, metals and chemicals that are in it. You may not realize it, but bottled water is just as bad. There are no requirements in place that force bottled water companies to filter or treat the water that they sell. So what are we supposed to do?

OSMOSIS

You may have heard of reverse osmosis water treatment systems as a purification method. The problem with a reverse osmosis treatment system is that it removes all of the "good stuff" - the healthy and essential minerals that your body needs and leaves the "bad stuff" - the lead, mercury, chemicals, pesticides and herbicides.

The reverse osmosis method removes molecules based on their size. Any molecules that are larger than a water molecule is removed from the water. Unfortunately, many harmful chemicals are smaller than water molecules, as are pesticides and herbicides. Healthy minerals like calcium, magnesium and potassium are also larger than water, so they are stripped out too.

What happens when we drink water that has been treated with a of reverse osmosis water treatment system?

When water is stripped of essential minerals, over time as you drink it, it actually pulls minerals out of your teeth and bones. It also will absorb any chemicals in the air once it is exposed to air. The water then becomes to acidic to be healthy, not to mention all of the chemicals that are still in the water are causing cancer cells to develop in your body at an alarming rate.

The only way to get healthy, pure, good-tasting water is to filter it through a multi-layered filtration system. All water that you drink should be filtered with one of these types of filters, and if possible, any water that you use for anything at all should be filtered too.

Residential Reverse Osmosis Systems Are Great - NOT

Who needs residential reverse osmosis systems? That's a good question. So, far, I'm having trouble finding the answer.

osmosis jones dvd

Most of the new reverse osmosis systems residential units were designed for use on publicly treated water. But, people with publicly treated water don't need to use reverse osmosis. There is simply no reason for it.

OSMOSIS

I know that it can be confusing, because there's a lot of different information and varying opinions. But, if you read the Environmental Protection Agency's recommendations, you will see that residential reverse osmosis systems are only suggested as one option for cyst removal.

Cysts are microscopic organisms that cause diarrhea, stomach cramping, vomiting, loss of appetite and other unpleasant symptoms. A strong person may only be sick for a few days, but a person with a weakened immune system or a small child can die from the infection.

The EPA states that cysts may be present in any publicly treated supply and even in bottled waters. Cysts may be ingested by drinking, brushing teeth or washing fresh fruits and vegetables with contaminated water.

The EPA recommends that "at-risk" individuals should use a residential RO system unit OR a purifier that includes submicron particle filtration. Submicron particle filtration costs a lot less than reverse osmosis systems residential units and they are just as effective.

For chlorine removal, the EPA recommends activated carbon. Now, some residential reverse osmosis systems include a carbon granule step, but many do not. It is typically an "additional option." So, if you do decide to use RO, you need to make sure that you add the step.

There are a number of contaminants that the EPA is not particularly concerned with, primarily, because they don't cause "immediate" illness. If you want to protect your long term health, however, you should be concerned about those contaminants.

Consider the heavy metal lead, for example. The EPA has created a "federal action level" for lead content, which simply means that if a facility determines that the levels have risen above the action level, steps must be taken to correct the problem.

Reverse osmosis systems residential products only reduce lead to the federal action level, but there is really no safe level for lead consumption. The metal builds up in the body overtime, causing heart disease, high blood pressure, osteoporosis and other long term health problems. Not to mention the affect that it has on the human brain.

Instead of choosing residential reverse osmosis systems for lead reduction, you should choose ion exchange. Home purifiers that include ion exchange, submicron filtration and carbon blocks will reduce all of the contaminants mentioned here by at least 99%.

There are other reasons to avoid reverse osmosis systems. The units break down easily and require extensive maintenance. They create gallons of wastewater when functioning properly and provide no protection when they are dysfunctional.

The cheaper residential reverse osmosis systems are simply not a worthwhile investment. Multi-stage, selective filtration is the right answer for most of us. That's what you need to look for.

Reverse Osmosis Reviews - A Tale of Two Systems

Here, you have a reverse osmosis water treatment comparison that's a little different. Using reverse osmosis reviews and facts that I've learned through research, I compared the effectiveness and cost of the Ever-pure under the counter system to a multi-stage selective filtration device that makes use of sub micron filtration, but not RO.

osmosis water filter

Of course, there are many different kinds of systems on the market and you might be looking for a "whole-house" reverse osmosis water treatment comparison. But, regardless of the "type" of measures that you plan to take, I believe that you will find this information helpful.

OSMOSIS

Contaminant Removal

Customers rarely talk about contaminant removal in reverse osmosis reviews. You have to look for product performance data to get that information. According to their website, the Ever-pure company has a system that fits under the kitchen counter and reduces the most common contaminants in publicly treated supplies.

All of the under-counter and other kitchen systems are designed for publicly treated supplies. Even some of the larger systems like GE's "Smart Water" are designed for the homeowner that is serviced by their local water authority. None of these systems are effective for someone that has a high sediment, sodium or bacterial content. If you have a private well, you should have testing conducted and choose your system based on the contaminants that are found.

I have read reverse osmosis reviews in which consumers complained that they could still taste chlorine. That's because the system that they chose did not include the necessary steps to remove it. That's why I chose Ever-pure for this reverse osmosis water treatment comparison.

It is the only one that includes the necessary steps to reduce chlorine and its byproducts (THMs), as well as VOCs, lead and cysts. Now, it only reduces lead to the federal action level. A multi-stage system that includes ion exchange can reduce lead by more than 99%.

The company does not mention the percentage by which other contaminants are reduced. But, with the best multi-stage selective filtration devices, all of the common contaminants are reduced by at least 99%.

One of the most frequent complains in reverse osmosis reviews concerns how much the systems cost. So, here's a look at what you might run into.

Costs

Cost is usually the primary topic in a reverse osmosis water treatment comparison. In truth, the more expensive systems are the most effective for private well owners and others that need them. But, when it comes to publicly treated supplies, the costs are unnecessary.

The Ever-pure under-the-counter system costs nearly 0 to purchase. The most effective selective filtration devices cost less than 0. Percentage-wise, the price difference is similar, regardless of the type of system that you need. It will cost at least four times as much, usually more, to include a reverse osmosis step.

These are the things that I've learned from reverse osmosis reviews and from personal use. Hopefully, this reverse osmosis water treatment comparison will help you make the right choice.

The Disadvantages of Reverse Osmosis Water Purification Systems

By now, most of us have probably heard that we should all be drinking a lot of water to maintain our bodily systems and stay healthy, and by concerns of the true quality of bottled water, we are heeding the call.

osmosis replenish

In today's society, most of us are becoming more concerned about, and aware of, ways to improve our overall health, and water is definitely right up there at the top of the list of concerns.

OSMOSIS

Not only should we be concerned about how much water we are ingesting, however. We should also be concerned about the quality of that water. As such, may of us are choosing to learn more about water purification and filtering to ensure that the water we drink, cook with, and bathe in is pure and clean.

There are many systems out there, one of which is the reverse osmosis type, which claims to be the best on the market, but there are distinct disadvantages of reverse osmosis (also referred to as ro).

If you are like most of us, cost is a consideration for just about everything, and water purification is no exception. ro systems are incredibly expensive. They are priced in the thousands of dollars, which is one of the biggest disadvantages for most people. They are simply not affordable.

Okay, let's assume that price does not really matter, and tend to the question: Does it make water safe to drink? Well, despite the overwhelming popularity of these systems and the claims made by manufacturers, the answer to that question is no, not really.

These systems are really designed to remove anything that is heavier than the water itself. What is heavier than water? Dirt. So, it's great at removing dirt from the water. The problem is, very few people have water with dirt in it coming out of their kitchen faucets, so what good is that? For most people, the ability to remove sand or dirt is not at all useful.

What else is heavier than water? Lots of minerals are heavier than water. Wait a minute! Minerals? Aren't we supposed to be getting minerals? Yes, our bodies need minerals; in fact, most of us take a daily vitamin and mineral supplement. We actually pay money to add minerals into our diets, and reverse osmosis manufacturers would have us pay thousands of dollars to remove minerals from the water we drink? That defies logic.

What about chlorine, that chemical that bleaches out our swimsuits when we swim in the pool and leaves our water tasting nasty and smelling worse? Does reverse osmosis eliminate chlorine? Well, to be sure, our municipal water treatment plants have been using chlorine for decades, and chlorine is known to kill bacteria; however, chlorine is not natural and not pleasant to drink.

Unfortunately, chlorine remains behind, which is another of the disadvantages of reverse osmosis water systems. Overall, ro systems are too expensive and too ineffective.

Getting cleaner, purer, safer water into our bodies is a top priority and, with a little research, there are better choices for you and your family.

The Disadvantages of Reverse Osmosis Water Purification Systems

Residential Reverse Osmosis Systems Exposed

Residential reverse osmosis systems were all the rage at one time, but there popularity has waned over the years. Industries are successful with reverse osmosis systems residential homes, however, are not so successful.

osmosis water system

Companies that sell reverse osmosis systems claim that they are the latest technology. They have actually been in use for over 50 years. They are a common component of public filtration plants. They are the only choice for desalination facilities. But, in they are only one step in the process. In other words, additional steps are needed to make the water safe and drinkable.

OSMOSIS

In most cases, reverse osmosis systems residential customers are buying something that they do not need. Some wells that are brackish may require RO, but once again, it alone does not make it safe to drink.

There are many contaminants that reverse type systems will not remove. Most of them are chemicals, but bacterial organisms pass through the membranes, as well. For well-water, a disinfection process is still required, typically involving the use of chlorine. Then a carbon filter must be used to remove the chlorine and another type must be used to remove by-products of chlorination called THMs.

Bacterial removal protects your immediate health. Chemicals, chlorine and THMs are threats to your future health. Many of them are known to cause cancer, either in animals or humans or both. Continuous exposure throughout one's life increases the risk of cancer by several hundred times, according to scientific research.

Osmosis systems will neither protect your immediate or your future health. But, one of the biggest reasons for their decrease in popularity is the fact that they de-mineralize. Several books have been published about the health giving qualities of pure water, but all of them mention that drinking distilled or de-mineralized is bad for your digestion and can lead to mineral deficiencies, over time.

Industries that need demineralization rely on reverse osmosis systems residential units, on the other hand, are now offering to put the minerals back in, a process that was developed for use in desalination plants. Before, being sent to homes, it is re-mineralized.

Residential reverse osmosis systems are calling this "revitalization". I suppose it works in theory, but still seems illogical. Why would you pay extra for a system that does something you do not want and then "undoes" it?

The point is that there are some situations that benefit from reverse osmosis systems residential settings, however, are not on the list. Unless you require desalination, you can get a more effective, less expensive system for your home. The latest technology includes multi-media block, carbon filtration, micron removal and ion exchange. The result is safe, clean, perfectly balanced pH level and mineral content.

Micron removal blocks microscopic bacterial cysts and spores. Carbon filtration, as mentioned above removes chlorine and improves taste and smell. Multi-media blocks trap any chemical contaminants. Ion exchange balances, but does not destroy mineral content. Residential reverse osmosis systems start at ,000 and I haven't even covered all of the disadvantages. Suffice to say, it is not the right choice for most of us. For more information, please see my website listed below. Larry L. Taylor

Home Reverse Osmosis Systems - Are They Really Effective?

It's unbelievable how much misinformation is out there when it comes to water filters. So many people are led to believe that a home Reverse Osmosis system is exactly what they need to get pure, safe drinking water. Nothing could be further from the truth.

Fact is, a home reverse osmosis system can give your semi-pure water at best. Just think about the kinds of contaminants present in our tap water today. It's loaded with the normal dirt and grime, plus there are chemicals like chlorine and fluoride. Even pharmaceutical drugs can be found in this water.

INVERSE OSMOSIS

Add to this the heavy metals like lead and asbestos that get mixed in the water in the water supply system, and you get a dangerous mix of substances that can harm your health permanently.

Now, let's see what an RO system can do about these contaminants. The way these systems work is - there is a semi permeable membrane inside the filter through which water is forced to pass. The pores of the membrane do not allow contaminants to pass through. The only caveat is - the molecular size of the impurity should be greater than that of water.

So, theoretically, only water passes through this membrane and all contaminants are left behind.

The problem is - the molecular size of chemicals like chlorine or prescription drugs is smaller than that of water. So they also pass through undetected along with the water.

The other problem is of de-mineralization. Water in its natural state contains some minerals like calcium and magnesium which play an important role in our well being.

The molecules of these metals are big in size and are blocked by the membrane in your RO filter. Drinking this de-mineralized water can lead to health problems due to mineral deficiency in the long run.

Some home reverse osmosis systems try to remedy this by adding a separate unit to add minerals in the water after filtering, and then jack up the costs of the filter accordingly. It doesn't really make sense to first remove minerals from the water and then later add them - and that too at a higher cost!

Your best option is to use a filter that uses the advanced techniques of sub micron filtration, ion exchange, and carbon filtration. Together, these techniques remove the dirt, chemicals and heavy metals and give you really pure water - without de-mineralizing it.

So there you have it. A home reverse osmosis filter may not be the ideal choice for your health. Do some research and find out a better filter now.

INVERSE OSMOSIS

Residential Reverse Osmosis Systems

Residential systems are touted for their ability to reduce lead to the federal action level. If the lead in your water supply exceeds the federal action level, then you should complain to your community's public utility. It is the traces of lead that fall below the federal action level that are believed to cause chronic health problems such as digestive issues, memory loss and dementia in older people or those with weaker immune systems. Reverse osmosis water filter systems were originally used for desalination plants. They did a decent job there. Reverse was also used in the printing industry. However when the idea came up for residential reverse osmosis systems, there were several problems.

osmosis jones

Thankfully the usage of residential has declined. Treatment alone is simply not as good as other filter systems that exist. One of the replacements to residential reverse osmosis systems are carbon and multi-resin blocks can be constructed to include a sub-micron sized channel. It is certified to reduce cysts by 99% for six months and the replacement filters are very inexpensive. The best solution for lead reduction is ion exchange. It traps more than 99% of all of the tiny particles that are present in your water.

OSMOSIS

New residential reverse osmosis systems are slimmed down versions of the systems necessary to treat river or lake water in rural areas. Residential reverse osmosis systems do what they are supposed to do. They remove all trace minerals which is harmful to the health of people. People need trace minerals in their drinking water. It's better for their health and the water taste fresher. In areas where people are the healthiest, the water has naturally balanced trace minerals including potassium, calcium, sodium and others.

Home Reverse Osmosis Systems

When deciding on purchasing any home reverse osmosis systems, be sure you know what type of membrane you will need. Different water treatment chemicals will affect the membrane differently. If you have city water, call your water department to find out, if you have a well, have your water tested. Your county Health Department should be able to either do this, or direct you to where it can be done. Once you have the results, it's time to decide on a solution. Knowing what is in the water coming to your home will give you a better idea of the options available for removing them.

osmosis jones dvd

The reverse osmosis system consists of a prefilter to remove silt and sediment, then the water is forced through a membrane that removes microscopic impurities. The water is then filtered again, and in some cases the use of ultra violet is employed to kill bacteria, then the water is filtered yet again. If your water pressure isn't sufficient to force it through the membrane effectively, a booster pump will be needed. The impurities, along with untreated water, are then flushed out the waste water pipe.

OSMOSIS

This can also be redirected to water landscaping and plants so no water gets wasted. This process is, to date, the preferred method of removing trace amounts of medications, both prescription and over the counter, that are appearing with more frequency in our water treatment facilities. So home reverse osmosis systems make sense if your water is contaminated with these impurities.

Reverse Osmosis Water Treatment Systems

Reverse osmosis are not all they are cracked up to be. Research has shown that drinking water that has been de-mineralized on a day to day to basis will cause digestive problems and nutritional deficiencies. Not having the proper trace minerals in your diet, such as sodium, calcium or potassium, can lead to cancer. Reverse specialize in de-mineralizing the water that passes through them. The only health benefit that might be gained from reverse osmosis is in the area of kidney dialysis. For dialysis, the water must be completely free of all solid impurities and reverse osmosis water treatment systems do this well.

osmosis membrane

Reverse are unable to filter chemical pollutants are present all through the environmnent. Most synthetic chemicals, such as chlorine or drugs have smaller molecular structures than water, therefore they are not removed when water passes through the membranes of reverse osmosis water treatment systems. There have been over a thousand synthetic, cancer causing chemicals found in tested tap water. None of these were removed after reverse osmosis.

OSMOSIS

Not just chemicals get through, also bacteria. Osmosis water treatment systems can stop cyst bacteria. However, the membranes of water treatment systems can rip without notice and allow cysts in their spore stage to enter into the usually filtered water. Cyst contamination is possible at any water source. When people ingest cysts, they can get sick and have any number of digestive system problems. In those with weak immune systems, cysts can even cause death.Its upto you to decide now.

Reverse Osmosis Home Systems

Reverse osmosis home systems, like distillers, were popular, at one time, but not so much today. There is an ongoing debate over the long term health effects of drinking distilled or reverse osmosis water, rather than filtered water with trace minerals.

osmosis jones

You see both reverse osmosis home systems and distillers de-mineralize the water. That is, the natural trace minerals that are important to our health are removed by these systems. In some industries, such as film processing, de-mineralized water is a necessity and that's what the systems were originally designed for.

OSMOSIS

The fact that none of the leading brands are reverse osmosis home systems should tell you something. It's just an unnecessary expense for most people. The only reasonable use is in homes with well water that tends to be brackish or salty. An ion exchange filter would probably take care of even that.

There are some studies that claim drinking reverse osmosis water is "okay". But experienced water specialists believe that drinking naturally balanced water, with trace minerals intact, is best for your health.

For one thing, de-mineralized water is completely unnatural. Nowhere in the world will you find naturally occurring water that does not contain trace minerals like calcium, magnesium and potassium. Instead of reverse osmosis home systems, you should be looking for a product that will balance the mineral content of your water, as well as the pH level.

Reverse osmosis water is acidic. A number of studies suggest that cancer cells grow only in acidic environments. Supporting evidence is found in the fact that people who live the longest and have the least diseases live in areas where the water has more of an alkaline pH, in other words, a higher mineral content.

In the "Joy of Health", Dr. Zolton Rana has this to say, "The longer one consumes distilled water, the more likely the development of mineral deficiencies and an acid state." The water that comes from reverse osmosis home systems is just like distilled water, in terms of mineral content and pH level.

In "How to get Well", Dr. Paavo Airola, an oncologist and cancer expert, says that "long term consumption of distilled water eventually results in multiple mineral deficiencies". In order to function properly, our bodies need minerals. In order for our bones and joints to be healthy, we need minerals. One of the best natural sources of trace minerals is water, but not "reverse osmosis water".

Reverse osmosis water filters waste water. They are expensive initially and expensive to maintain. The membranes inside of the units are delicate and prone to manufacturer defect. Replacing them is difficult, because they tear easily.

You deserved to drink, shower and live with clean healthy water. Reverse osmosis home systems don't even remove chlorine. So, think, before you buy. Now you know the facts.

Reverse Osmosis Water Units - These Systems Have Problems

Reverse osmosis water units are expensive and for most homeowners, there is no need to spend the money. While those that market them may say that reverse osmosis systemes are the best, there are better, more technologically advanced alternatives.

osmosis replenish

Reverse osmosis water units have been recommended for giardia and cryptosporidium cyst removal. In case you are not familiar with them, cysts cause waterborne illnesses similar to food poisoning. They can cause chronic stomach problems as well. In people with poorly functioning immune systems, they can cause death. Any system that is certified to filter down to one micron will remove cysts. The best ones filter down to a half a micron.

OSMOSIS

Reverse osmosis systems are sometimes recommended for people that have "hard water" which is a high mineral content. Generally, the mineral is calcium, but iron and other elements can cause problems as well. Water softeners are less expensive than reverse osmosis systems, as is ion exchange. Either of those can be targeted to address specific minerals and other elements without completely de-mineralizing. Drinking de-mineralized water on a regular basis is not good for your health.

Reverse osmosis water units are sometimes recommended for lead reduction. Ion exchange systems trap lead, copper, and other metallic ions and replace them with sodium or potassium. Those electrolytes help to maintain the body's homeostasis or hydration.

In most homes, the biggest problems are chemical contaminants, including chlorine and chorine byproducts known as THMs. In some areas, VOCs, such as perchlorate, are problems. Traces of pesticides, herbicides, and prescription drugs have been found coming in to many homes and offices.

Reverse osmosis systems will not remove those chemicals at all. They are smaller than your water's molecules. Anything that would filter them out would not allow water to pass through either. Chemicals can only be trapped on the surface of carbon granules and special resins. The process is called adsorption.

The quality of adsorptive purifiers varies. It's best to read product performance data before you buy one. The manufacturer should list the impurities that are reduced and the extent of reduction. Most reverse osmosis water units don't include the extent of reduction, because they don't have the testing done. Manufacturers can have Underwriter's and other independent laboratories conduct testing, but they must pay for it. Many companies don't want to go to the expense.

If your problem is fluoride, reverse osmosis systems are mostly ineffective. The highest fluoride reduction is provided by granulated aluminum. But, granular carbon is somewhat effective as well.

If you have a private well, then you should have regular testing conducted to determine the impurities that are present. Even after you install a system, you should have annual testing conducted to create a record of quality. There are industrial and natural activities that can affect that quality.

If you have access to a public waterline, you don't need reverse osmosis water units. You need multi-stage selective filtration, which is far less expensive.

The Truth About Reverse Osmosis Systems

The dictionary definition of osmosis is a "slow change in concentration: the diffusion of a solvent through a semipermeable membrane from a dilute to a more concentrated solution."
The definition of Reverse Osmosis, also known as RO, is "the production of pure liquids: a process of purifying water or other liquids such as fruit juices by passing them through a semipermeable membrane that filters out unwanted substances". Osmosis is the reason why drinking salty water is deadly. If you were to you drink salty water and have it go into your stomach, the osmotic pressure begins to draw the water out of your body to try to dilute the salt in your stomach and eventually you start to dehydrate and could possibly die.

osmosis water system

The purified or pure water is collected from the clean side, or permeate side, of the membrane and on the other side is the water containing the concentrated contaminants which is flushed down the drain. The most common reverse osmosis system has a sediment/chlorine pre-filter, the reverse-osmosis membrane, a storage tank and an activated carbon post filter.

OSMOSIS

The reverse osmosis system removes salt and most inorganic materials that are present in the water. For this reason it is used in places where you find brackish or salty type water that contains nitrates or other dissolved minerals which are difficult to remove by other methods. It also removes the minerals from the water.

De-mineralized water contains more hydrogen and therefore, it is an acid solution where the pH is below seven. Consuming this acid substance causes our body to pull minerals from other sources, such as our teeth and bones to produce bicarbonate in an effort to neutralize the acid. This can be very negative. It has been proven that the production of free radicals goes up when body fluids are more acid than alkaline and this increases our risks for cancer.

All of our fresh water contains traces of minerals such as calcium, magnesium and potassium. I am not aware of any location on this planet earth where we can locate naturally occurring de-mineralization in the water. This makes me believe that we are meant to have these minerals. There are several studies and books written from a scientific view, that consumption of de-mineralized water can be dangerous over a long term and can result in multiple mineral deficiencies.

Many companies began marketing these reverse osmosis systems because of increased popularity and demand for water filtration products for the home. They advertised these systems as "state of the art" or "new" which is just not the case. The reverse osmosis system is often demonstrated using a device that measures the total dissolved solids or TDS or conductivity of the water. This tends to imply that this measurement shows the effectiveness of this reverse osmosis system to remove contaminants. But TDS meters measure the dissolved minerals in the water and have nothing, or very little, to do with the purity or the water or the contaminant levels.

I believe it is easy to determine which water filter system or reverse osmosis system is best for you if you take your time to compare each of the home water purifier systems data, performance, cost and ongoing cost per gallon.

Are Reverse Osmosis Water Systems Really Healthy For Home Use?

Have you ever wondered if reverse osmosis water systems make a good choice for protecting your family's health from the contaminants found in the tap water in our homes?

osmosis membrane

Well this information may be useful to you in making your decision.

OSMOSIS

Reverse osmosis water systems are used by some large scale treatment facilities and other industries as their primary means of removing minerals, metals and other contaminants that are "heavy". These facilities also use disinfectants like chlorine to protect us from diseases such as cholera.

But you may have heard a number of claims from companies touting these water systems for home use. Can they be trusted or is it advertising hype?

Let's find out by looking at a couple of these common claims made by the manufacturers of reverse osmosis water systems.

1. Reverse osmosis water systems can protect us from the contaminants that treatment facilities cannot. - This is untrue. There is only so much that the reverse osmosis process can do to protect us. It is not a catch all system and in fact in some cases, such as bacterial contamination, reverse osmosis systems must be teamed with other filtration systems to combat the contaminants.

2. Reverse osmosis water systems protect us from chlorine and its by-products (THMs) released when the chemical is used for disinfection. - Again, this is not true. Chlorine and THMs are too small and light to be trapped by the porous membrane. They pass right through, along with the liquid. You would have to have additional steps to block these contaminants, something like a carbon block, for example.

This may seem like an unimportant point to you and you may be asking why should we care about chlorine and THMs? Doesn't the government regulate them? Aren't they safe?

No, they are not safe.

Studies over the years have shown that the consumption of chlorine over a period of time causes long range chronic health problems and increases your risk of cancer. THMs have also been linked to cancer. The allowable "parts per million" content limit is the amount that is deemed safe for one time exposure in a 175 pound adult. No government agency has ever taken into account the fact that many of us weigh less. Nor, have they considered the effect of repeated constant exposure over the course of a lifetime.

When inhaled as vapors in your shower these contaminants aggravate various respiratory problems and can cause asthma attacks. Claims that a whole house reverse osmosis water system will prevent these problems are not true. Only an activated carbon shower head filter will block chlorine and only the best will remove THMs.

For the whole house, some effective units are available to remove these contaminants , but reverse osmosis water systems are not among them.

There are other disadvantages to the reverse osmosis water system. For instance, it is largely inefficient. It works by forcing pressurized liquids through a porous membrane. The size of the pores determines what contaminants will be removed. It is only semi-effective.

Also extra electricity is needed to run the reverse osmosis water system unit and pump. In addition this type of filter system is very wasteful, for every one gallon of water that is cleaned, several gallons end up as wastewater that gets flushed down a waste drain. And "clean" is used loosely, here. Reverse osmosis water systems also reduce the pressure throughout your home because they are inherently slow. It may never be possible for you to take a pulsating shower again.

The last disadvantage of reverse osmosis water systems, but not the least by far, is that the process removes nearly all of the minerals that naturally occur in ground-water. Even if you have the "hardest" water on earth, you do not want to drink de-mineralized water. It does not taste very fresh and is bad for your long term health, causing vitamin deficiencies and stomach ailments.

There are better options for your home than a reverse osmosis water system. The choice is yours; hopefully you'll make the right one.

Where Can I Buy Reverse Osmosis Water Systems?

Reverse osmosis is the process of filtering water to enable it for safe consumption. If you ask "where can I buy reverse osmosis water systems?", then you have to know that there are many places where you can actually buy them. Many retailers carry systems for reverse osmosis and some of the sites that offer such products include Sears.com, Quenchonline.com, Purewaterexpress.com and also Culligan.com. It is important, however, that you check a certain system for NSF rating to guarantee efficiency of contaminant removal. Many consumers and homeowners choose to invest their money in a good reverse osmosis system especially if it means drinking safe water each day.

Buying a system for water purifying is a good investment to consider as this can mean healthy and clean drinking water for the family. You can be assured that your water is not just odor-free but also microorganism and pathogen free. You would not have to worry about harmful health and body effects that can lead to infection or sickness.

Before buying any water filtration system, it is wise to do some research even if it just means comparing systems sold in the market. That way, you can easily be at ease with the water you use and drink each day. You can have the peace of mind not just for the water you drink but also for the water you use for bathing, cleaning and cooking.

Residential Reverse Osmosis Systems Explained

Some people recommend residential reverse osmosis systems as a water purification method for homeowners. From what I have read, there seem to always be better options than reverse osmosis systems residential units.

You see, this purification method has many disadvantages. Residential reverse osmosis systems are large, expensive, wasteful, unnecessary and ineffective against certain types of contaminants.

OSMOSIS

The size may not be important to you, but even the compact version that some companies offer for "under-the-counter" purification requires adequate space for mounting and a drainage pipe for discharging wastewater.

Price is important to most people. If it were the most effective purification method on the market, then reverse osmosis systems residential products would be worth the price, but there are always less expensive options that do as much or more than these products do.

For example, the least expensive under-the-counter system currently retails for around 0. The manufacturer added a granulated carbon step, so it removes chlorine. But, other than that, it only removes lead and cysts.

There are hundreds of cancer causing chemicals in today's surface and groundwater. Reverse osmosis systems residential treatment removes none of them. Lead can be removed through ion exchange. Cysts can be removed with a micron particle filter. Chlorine is, of course removed with granulated carbon.

You can get a kitchen countertop selective filtration device with all of those steps and an adsorptive block to remove those cancer causing chemicals for less than half the price of the least expensive residential reverse osmosis systems. Replacement filters cost twice as much. The cost per gallon is twice as much.

Depending on the unit you choose, you could need to call both a plumber and an electrician for installation. If you don't have a drain available for use, one will have to be installed. Any homeowner can install the kitchen countertop purifier that I mentioned with minimal effort. Why pay for all of this, when you don't have to?

The wastewater created by reverse osmosis systems residential designs is enough to frustrate most homeowners. Water bills go up, so that's another expense. If the system leaks, you've got a real mess on your hands. And, there's still one more disadvantage.

Residential reverse osmosis systems remove any naturally occurring mineral content that is present in your source. All surface and groundwater has some natural mineral content. With selective filtration, you remove all of the health hazards and everything that ruins the taste without destroying the mineral content.

Drinking de-mineralized water is like drinking distilled. It's bad for the digestive system and can cause mineral deficiencies, which would affect the health of your bones, among other things.

Some people recommend reverse osmosis systems residential devices for hard water problems. Ion exchange is a better solution. It balances mineral content, removes lead and other metallic ions and replaces them with the electrolytes sodium and potassium. The taste cannot be beaten.

Taste is something that I forgot to mention about residential reverse osmosis systems. The water tastes stale like distilled. It's just not a good product.

Residential Reverse Osmosis Systems - What You Need to Know

If you believe what the marketers of residential reverse osmosis systems are saying, you would think that you had a revolutionary piece of equipment at your fingertips. The only problem is that the reverse osmosis systems residential benefits have not quite been what people had expected.

osmosis membrane

Residential reverse osmosis systems are revolutionary only because they are the first RO systems built for home instead of industrial use. RO has been a standard water treatment method in the industrial world for quite some time. It is used in order to keep mineral deposits from forming in machines such as boilers.

OSMOSIS

The reverse osmosis systems residential applications have only recently begun to be explored. Touted as a water purifying system, it is basically a scaled down version of the filter that they use at the treatment facilities. This filtering system leaves a lot to be desired in the way of water treatment, even at that level.

Even though the idea of residential reverse osmosis systems is a relatively new one, the RO system has actually been utilized for water treatment for over a century. First introduced in order to slow down the death rate from waterborne diseases, the system only worked moderately well. It wasn't until chlorine was introduced in 1908 that the apparatus began to be effective.

The problem with RO system is that it is not of the design to be an effective water cleaning apparatus. The porous membrane filter is a capable de-mineralization tool, but it is not effective in the removal of anything smaller or lighter than a water molecule. This shortcoming is something that reverse osmosis systems residential owners aren't finding out about it until it is too late.

There are many toxic chemicals flowing through our drinking water system, and most of them flow through the filter along with the water. So does a horde of bacterial agents, far too small for the membrane to capture. The big worry that owners of residential reverse osmosis systems have is that their system will also be helpless to thwart these contaminants.

It would be a safe assumption that if the RO system at the water treatment facility failed in its mission to halt the flow of these toxins, that residential reverse osmosis systems don't stand a chance at stopping them. That is because the RO system is really only the first section of what needs to be a multi pronged attack in combating today's modern contaminants.

Had many of the reverse osmosis systems residential owners done their homework before they bought their unit, they would have known that it was not what they needed. They would have realized that there are whole house and point of use filtering systems that they could have gotten at a fraction of the price that they paid.

Residential reverse osmosis systems are not the answer. What is necessary in combating chemicals in your drinking water is the combination of an activated carbon filter and a multi block filter. Add to these a sub-micron filter and an ion exchange unit, and you have all the water purifying system that you'll ever need.

The Health Through Reverse Osmosis Myth - Why Home Reverse Osmosis Systems May Not Be For You!

You've probably seen ads from time to time stating that you can achieve better health through reverse osmosis. That would be great if it was at all true, but it isn't. These are simply falsehoods presented to you by the marketing agents in order to sell you a home reverse osmosis system.

The only field that has been able to derive any benefit to health through reverse osmosis is medical kidney dialysis. Although the processes are very similar, they are still only remotely comparable.

OSMOSIS

Water treatment centers use reverse osmosis to remove mineralized or seeable debris from our water, but without further filtering for chemicals, metals, and parasites, the system doesn't render water safe to drink. If a treatment facility can't get the job done using the same equipment, what would lead you to believe that a home reverse osmosis system is going to do any better?

There is a multi-layered filtering system necessary to totally clean and purify your water of which a home reverse osmosis system is only the first step. It is ineffective and an inefficient means of cleaning your water. The systems are costly at about ,000 at base price, and are terribly wasteful. Five gallons of water are wasted for about every gallon cleaned. Although the companies will tell you that their home reverse osmosis systems will in fact effectively block out 99%of all contaminants from entering your home.

Since the system is only designed to stop objects with a greater molecular weight than water, hence a mineral, everything else flows through unscathed. This allows chlorine and other toxic chemicals, liquid pesticides, liquid coolants, and microscopic organisms not only entry into your home, but directly into your drinking glass.

We touched earlier on the huge price of the system itself, but we forgot to mention a couple of other things. The system has got to be professionally installed. Since none of the manufacturers we looked up offered installation services you're going to have to hire a plumber. Have you seen how much those guys charge? When you hire the plumber, make sure that he's someone with whom you can get along. You're going to be seeing him again.

Why would we say that? The truth is that the membrane filter system needs constant maintenance, and even still, the filters need to be replaced fairly often. You see, even your wallet can't maintain good health through reverse osmosis.

If you're not convinced not to buy a home reverse osmosis system yet maybe this will push you over the edge. If you talk to a representative of your local treatment facility, they will tell you that your best bet is to buy bottled water! Surprised? Confused? You shouldn't be.

Reverse osmosis de-mineralizes the water. The human body needs trace minerals to maintain health. The bottled water, although purified tap water mostly, has had these necessary minerals put back in.

So, you see, you truly cannot even maintain health through reverse osmosis, let alone improve it.
