The most common method used by premium bottled companies to purify water is reverse osmosis RO. It also goes by the name hyperfiltration and it is the finest filtration known today. It is used to purify or clean a variety of contaminants. Particles as tiny as ions will be removed easily using this method of water purification. With this method, the following pollutants are effectively removed. They are arsenic, bacteria and viruses, bad tastes and odors, heavy metals, chlorine, fluoride, nitrates, sediment and iron.
Reverse osmosis will significantly reduce hydrogen sulfide. However, it does not actively remove radon and this is worth a note. To ensure that it works perfectly, ultra violet purification can also be considered. This method comes with many merits and the following are the top two advantages.
OSMOSIS
As stated above, this is a method known to eliminate or purify a wide variety of pollutants and contaminants. This is always a good thing because it makes it a sure way to get water clean for usage. Another thing is that reverse osmosis is pretty cost effective and is implemented without major hassle.
Some of the downsides to RO include the need for sediment and carbon pre-filtration. This is done to prevent membrane fouling. Another disadvantage to this method is that it is fairly slow owed to it working against osmotic pressure.
Reverse osmosis membrane should last anything from 2 to 3 years. This is taking into consideration good maintenance of your sediment and carbon pre-filters. At home, you will need to know the amount of purified water a home RO system can produce. Many can produce up to 50 gallons per day and if upgraded this could go up to 100 gallons per day.
