Reverse Osmosis (RO) Systems

Reverse osmosis (RO) is a special type of filtration that uses a semi-permeable, thin membrane with pores small enough to pass pure water through while rejecting larger molecules such as dissolved salts (ions) and other impurities such as bacteria. Reverse osmosis is used to produce highly purified water for drinking water systems, industrial boilers, food and beverage processing, cosmetics, pharmaceutical production, seawater desalination, and many other applications. In an RO system, pressure (usually from a pump) is used to overcome natural osmotic pressure, forcing feed water with its load of dissolved salts and other impurities through a highly sophisticated semi permeable membrane that removes a high percentage of the impurities. The product of this process is highly purified water.
