The effect of varying the temperature of the feed water for reverse osmosis was studied for two aqueous solutions, one with a relatively high concentration of NaCl (5 gll) and the second with a low salt concentration (0.8 g/1) . The feed temperature was varied between 12-30ยฐC and pressures of 20, 40

Thin-film composite reverse osmosis membranes of polyamides were prepared by interfacial polymerization. Various benzenediamines and poly(aminostyrene) were interfacially reacted with various acyl chlorides to prepare a skin layer of composite membranes. Among the membranes prepared from the structu
Several sets of porous cellulose acetate membranes were made using the same casting solution composition and gelation conditions but varying the casting solution temperature and solvent evaporation conditions. The films were tested in reverse osmosis experiments at 250 psig using aqueous feed soluti
