Reverse Osmosis Systems

Recognized by the Centers for Disease Control and the Environmental Protection Agency as an effective means for treating drinking water, reverse osmosis systems process water by using pressure to force the water through a very fine, semi-permeable membrane.

Usually, RO systems are comprised of a prefilter, a membrane and a postfilter, although some also offer various advanced filtration options. In the RO system, the prefilter removes larger particles from the water before it travels to the membrane. Then, the water is forced through the membrane, leaving behind the impurities that were in the water.

Since the process takes time, a small tank stores the purified water until it’s needed. But before the water is dispensed from the dedicated faucet, it runs through a postfilter to remove any remaining tastes or smells. Water produced via reverse osmosis very nearly reaches the purity of distilled water but in a much shorter time and without using any electricity.
