Development of reverse osmosis membranes and spiral design modules for economic demineralization of brackish waters at low pressures
Part 1 describes work directed toward the development of a low-pressure membrane for the desalination of brackish waters. The membranes developed are capable of producing between 20 and 25 gallons of permeate per square foot of membrane area per day with an 85 % rejection of chloride ion when tested on a feedwater of 3500 mg/l sodium chloride and at feed pressure of 300 psig. Part 2 describes work directed toward manufacturing fabric-supported membranes and incorporating these into spiral wound reverse osmosis membrane elements. The elements fabricated with this membranefabric composite were capable of water flux rates between 14 and 20 gal sq ft/day with chloride ion rejections between 80 % and 60 % and magnesium ion rejection in excess of 95 % when tested at 200 psig on a feedwater containing 2000 mg/l sodium chloride and 1000 mg/l magnesium sulfate.
