Work was directed toward improvement of semipermeable membranes for use in reverse osmosis desalination systems. Inclusion of pyridine as a constituent in the membrane casting solution has resulted in appreciable increased membrane strength. Design criteria for various systems for desalting sea water, based on present technology, were evaluated. It is proposed to use a two pass system with sea water initially passed through membranes at 1200 psi to produce an intermediate water of about 5,000 ppm. This intermediate water is stored as produced and, in a predetermined time cycle, is used as feed for the same membrane units on a time shared basis, to produce product water of less than 500 ppm TDS.
