Many of us take it for granted that the water we get from our kitchen sink is safe to drink and cook with.  However, some of us are not so fortunate and may have to install water filtration systems to remove impurities which may cause us harm, perhaps not immediately, but gradually as toxic substances in our drinking water may accumulate in our bodies over time.  For people who are concerned about the health risk of their home water supply, they may want to consider looking at installing a reverse osmosis system.

At the heart of the reverse osmosis system is the membrane.  The size of the pores in the membrane is .001 microns.  Many of the impurities found in water such as bacteria, pyrogens, viruses, pesticides, hydrocarbons, radioactive contaminants, turbidity, colloidal matter, chlorine, detergents, industrial wastes, asbestos, dissolved solids, sodium, calcium, magnesium, sulfates and cadmium will not pass this barrier.  Instead, they are drained out.  What passes through is pure water.

Various pre-filters and post filters connect with this membrane.  Pre-filters remove sand, silt, dirt and other sediment.  Carbon pre-filters may be necessary to remove chlorine which may damage membranes that are made of thin film composite TFC or thin film material TFM.  Carbon post filters remove remaining tastes and odors just before the water reaches the faucet.

Reverse osmosis systems operate in the same way and look very much alike.  They also use the same basic components.  The only difference in RO systems is in the quality of the filters and membranes they use.  When shopping for a reverse osmosis system and having it installed, home owners should first find adequate solutions for their water quality problem before making a serious commitment.  RO systems must be maintained to insure water quality.  That means parts and filters will need to be replaced on a regular basis.  You must be aware of these ongoing costs and be ready to keep the system operating smoothly.
