Enviro~Tech Systems & Engineers. Reverse Osmosis or R.O. is a vital step in a complete water purification procedure. Reverse Osmosis removes salts, microorganisms and many high molecular weight organics from water. Unlike conventional filtration, Reverse Osmosis is a membrane separation process in which, the feed water flows under pressure into the semi permeable membrane and separates into two streams. The purified water or permeate passes through the membrane, while the concentrate water or reject water, containing dissolved and un dissolved salts, that does not flow through the membrane, is discharged to drain.

The reverse Osmosis systems are field proven, highly reliable and a cost effective solution to treat a wide range of brackish waters. Designed with flexibility, reverse Osmosis systems utilize. State-of-The art spiral wound reverse osmosis membranes to suit a given application. These systems can remove 90-98% of total dissolved salts. RO capacity depends on the water temperature, total dissolved solids in feed water, operating pressure and the overall recovery of the system.
