Why reverse osmosis water purification systems are used

It is simple to understand why reverse osmosis water purification systems are used when you see the efficient way they destroy germs, micro-organisms etc in the water. These days it is necessary to install a water purification system in your home to ensure safe and pure drinking water for your family. Water sources and water supply all over the world are getting contaminated and need to be treated and purified. It is therefore essential to install the right type of water purification system in your home.

Before buying a water purification system it is a good idea to do research on the various types of purification systems available in the market. It is also a wise thing to read customer reviews in order to get information on possible problems, flaws etc that can crop up and to compare prices of various systems.

Water purification systems are used commonly these days to treat drinking water. The reverse osmosis water purification system passes the water through filters that remove large suspended particulate matter and harmful pollutants and chemicals, and then forces the water through a plastic membrane that filters out tiny contaminants.

The well or tap water first goes through the sediment filter in the filtration stage where sediment, silt and sand/clay particles are removed. Then the water in forced through a carbon high efficiency filter block where carbon that is micro-pulverized adsorbs pesticides, chloramines, chlorine and other pollutants/organic chemicals etc efficiently. The next step in the process is to pass the pre-filtered water which is devoid of chemicals and particles into a reverse osmosis module where the molecules of pure water are forced through the reverse osmosis membrane flushing out the hardness, salts, viruses, bacteria, pyrogens and similar impurities from the water.

One of the drawbacks of the reverse osmosis water purification system is the “waste water”. For every gallon of water that is produced, two to four gallons or even more water is wasted. Nevertheless, this type of water purification process is a good alternative as they produce a gallon of water for only about .5 cents and the reverse osmosis membranes last for almost 5000 to 10000 gallons of water if used properly.

Reverse osmosis water purification systems will produce filtered water according to the amount of dissolved solids in the water, type of water quality, low or high pressure etc. The types of membranes used are Cellulose Triacetate (CTA) or Thin Film Composite (TFC). CTA membranes remove around 90% of pollutants and impurities and when combined with an activated carbon filter it provides you with all the filtered water you need. The TFC membrane needs carbon filtration in front of the membrane so as to remove the chlorine in the water. Chlorine can spoil/ruin the membrane. All the water has to flow through the carbon filter thus requiring frequent changes of the filter. This membrane removes more pollutants that the other membrane.
