REVERSE OSMOSIS SYSTEM 3 FILTERS 190L/GGReverse osmosis is a technology that takes advantage of the ability of certain semi permeable membranes to separate dissolved substances from water. The pressure of the water supply forces the water through the membrane; the pure water (filtered) is so separated from the water containing dissolved salts (concentrate). The highest performing osmotic membranes (those constructed with polyamide and polysulphone) act as a bar rier not only for salts and
