Reverse Osmosis (RO) is a water treatment process that removes contaminants from water by using pressure to force water molecules through a semipermeable membrane. During this process, the contaminants are filtered out and flushed away, leaving clean, delicious drinking water.

RO system is widely used in water treatment, purification for tap water, well water, underground water, borehole salty water, brackish water and seawater, pure water and ultra-pure water production. Application area such as, food processing, bottled drinking water, home use drinking water, power stations, electronic industries, cosmetics production, pharmaceuticals manufactories, and medical treatment(such as hemodialysis). It is a key equipment for pure water plant and ultrapure water equipment.
