Reverse osmosis membranes are used widely for brackish water desalination. CSM brackish water RO membrane is especially more effective when the feed water is within 10,000 ppm of concentration. Because of its high performance rate and chemical resistance, it can be used for a variety of purposes. It is used in producing drinking water, industrial water, pharmaceutical water, waste water treatment and concentration of food and/or medicine
