Reverse osmosis process uses semi permeable spiral wound membranes to separate and remove dissolved solids, organic, pyrogens, sub micron colloidal matter and bacteria from water. Feed water is delivered under a pressure of approximately 16 kg/cm2 through reverse osmosis membranes. Water permeates the minute pores of the membrane and is delivered as purified water. Impurities in the water are concentrated in the reject stream and flushed to drain. Reverse osmosis is capable of removing 90-99% of total dissolved solids (TDS), 99% of organic, including pyrogens, and 99%bacterials in the feed water.
It is effective to remove asbestos, many taste, colour and odour producing chemicals, particulates, total dissolved ions (calcium,magnesium,sodium,ammonia, boron, chlorides, manganese, sodium, ammonium ions...), turbidity and radium.
RO system is widely used in water supply treatment, purification for tap water, and brackish water, pure water and ultrapure drinking water production, which can be the best choice for power stations, electronic industries,and medical residential areas. It is capable of removing more than 97% of total dissolved solids(TDS),about 99% of organic and bacteria in the feed/source water
