Reverse osmosis process uses semi permeable spiral wound membranes to separate and remove dissolved solids,organic, pyrogen, 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 pyrogen, and 99% bacterial in the feed water.
Brackish water, according to the organic content can be devided into surface water and ground water . surface water we can reverse osmosis system mating with relative sterilization system , ground water we can direct use reverse osmosis system , if Iron and Manganese overpass the inlet condition of RO ,we need add Manganese sand filter for pre treatment system , here also include the specific inlet condition of RO system for reference.







2>Product Description


The reverse osmosis device is an equipment to purify the saltine water with the action of pressure difference of semi permeable membrane. RO is also effective with asbestos, many taste, colour and odour producing chemicas, particulates, total dissolved solids, turbidity and radium. RO system is widely used in water supply treatment, purification for tap water, seawater and brackish water, pure water and ultra-pure drinking water production, power stations, electronic industries, medicine manufactories, and medical treatment. It is key equipment of pure water plant.

3>Process: Raw water ->Raw water tank -> Raw water pump -> Quartz sand filter -> Active carbon filter-> High pressure pump ->Security filter -> RO equipment->Pure water tank
