What Does Reverse Osmosis Do to Purify Water?

The question: what does reverse osmosis do is not a simple one to answer. Neither, is the question; what is reverse osmosis? But, I'll make an effort to explain.

Basically, it is a separation process. It can be used for many different purposes. It is the opposite of "osmosis" or diffusion, which is a process that occurs throughout nature and is related to cellular or molecular activity. Reverse osmosis or RO is a man-made process.

What is reverse osmosis used for?

It can be used to remove salt from seawater and to de-mineralize waters for industrial applications. It is used in the maple syrup industry, at car washes, in the food industry and in kidney dialysis machines. It is used by wastewater treatment facilities and is often included as a step for drinking water treatment.

What does reverse osmosis do to maple syrup?

I thought you might find that interesting. When producers process sap to make syrup, they boil it down to reduce the liquid content and thicken it. The high temperatures need for thickening often resulted in ruined batches due to burning. This of course affected the taste.

In the 1970s, they learned that they could use RO to remove 75-80% of the water from the sap, so less boiling was needed and they were able to increase production. As with other applications, the semi-porous membranes must be closely monitored for bacterial contamination and damage.

What is reverse osmosis used for in other food industries?

Primarily, the process is used to concentrate beverages. For example, frozen concentrated orange juice manufacturers often use RO to reduce the liquid content of the juice. When you get it home, you add the amount of water that was removed by the process.

In the dairy industry, it is used to create concentrated milk and in the production of powdered milk. Although it cannot completely dehydrate a substance, it can typically reduce the liquid content by 70-80% making further steps less time consuming and extensive.

What does reverse osmosis do for car washes and other industries?

By removing the naturally occurring minerals present in surface and groundwater, cars dry without spots and manufacturing equipment is subject to less corrosion.

What is reverse osmosis used for in the home?

Some home purifiers make use of the step, but since the process removes all naturally occurring minerals, but not traces of chemical contaminants, such as chlorine, it is not a preferred system.

What does reverse osmosis do to drinking water?

It removes lead and other metals, which can be done with ion exchange. It removes minerals, which is not a desirable step; unless you have hard water and ion exchange can be used for softening. It removes cysts, which can be done with a micron filter. It's basically an expensive and unnecessary system for home purification.

I doubt if that completely answers the question of; what is reverse osmosis, as the whole thing is difficult to explain. But, for those of you who wondered what does reverse osmosis do, because you were looking for a home purification device, now you know there are better options.

Does Reverse Osmosis Remove Pharmaceuticals From Water?

Does reverse osmosis remove pharmaceuticals from water? A lot of people out there are counting on the answer to be yes. While Americans are more health conscious than ever, with organic natural products available almost everywhere nowadays and everyone is concerned with diet and exercise. This concern with what goes into their bodies includes water - and as many of us know, tap water may not be as safe as you may think. Studies on tap water have shown all sorts of different contaminants to be present: hormones, industrial toxins and contaminants, even pharmaceuticals in water supply.

That's right, pharmaceuticals. When people take over the counter or prescription drugs, part of those drugs are passed out of the body, resulting in having pharmaceuticals in water supply. Now does reverse osmosis remove pharmaceuticals from water? Fortunately, the answer is yes. Reverse osmosis does a pretty good job of removing these contaminants from water, just as it does with chlorine, toxins, heavy metals and other adulterants often found in tap water. So as far as pharmaceuticals in water supply are concerned, reverse osmosis performs well to keep these contaminants out of your water. It will also filter out all of those other things you don't want in your drinking water.

However, reverse osmosis is not optimal, as good of a job as it does of removing toxins like chlorine and adulterants like pharmaceuticals from your water supply. Reverse osmosis works by a process of using pressure to move water through a semi-permeable membrane which allows the water through, but filters out particulites and solutes from the water. Unfortunately, it also filters out some of the things you want in your water - the health giving minerals which your body is designed to absorb from your drinking water. These mineral nutrients are great for you and are readily taken up by your body from water. Robbing your water of these essential nutrients is really selling yourself short nutritionally.

Does reverse osmosis remove pharmaceuticals from water? Yes, absolutely - but it also removes the healthy mineral nutrients which you really need and should have in your water for drinking, cooking and bathing. Reverse osmosis does do a good job of getting the toxins, hormones and pharmaceuticals in water supply out of your water; however, demineralized water is not as good for you as water which still contains its minerals is. It's still not really water which you want to drink - and not the water you want for your health and that of your family. It's better than nothing, of course, but there are better options out there for you.

Today's health conscious lifestyles should always include the important element of pure, untainted drinking water. While organic foods and regular exercise are certainly healthy and important elements of maintaining good health, it is a mistake to neglect the water that you drink. If you are a person who is interested in better health (and it's safe to say that just about all of us are), than perhaps it's time you seek out a water filtration system for your home which will clear out pharmaceuticals in water supply and other toxins, but leave in the healthy minerals your body needs. It's the healthy thing to do for you and your family.
