What Is Reverse Osmosis and How It Works;
In short, it is the process by which water molecules are forced by pressure through a 0.0001-micron semi-permeable membrane by water pressure to force the water passing through the membrane, separating it from unwanted substances. The most amazing aspect of RO is that the substances left behind are automatically diverted to a waste drain so they don't build up in the system as with conventional filtering devices. This is accomplished by using a part of the unprocessed water (feed water) to carry away the rejected substances to the drain, thus keeping the membrane clean.
A reverse osmosis membrane reduces chemical quantities and most pollutants, including heavy metals like lead, fluoride, chromium, and arsenic. In addition, a reverse osmosis membrane will also remove nuclear radiation like plutonium as well as microbial contaminants such as bacteria and viruses.
Choosing an RO system; Homeowners who are thinking about buying a reverse osmosis system should determine their initial water quality and their goals in adding a water treatment system. The answers to the following questions will help homeowners choose an RO system.
