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
A two-stage method of making semi-permeable high flux reverse osmosis membranes was developed using water-ethanol mixtures to precipitate the cellulose acetate. This eliminated the need for heat treatment and produced membranes with fluxes up to 5 m'/m2 day and sodium chloride rejections up to 85 %
Annealing profiles are determined for two sets of cellulose acetate membranes originating from two different casting solution compositions under different casting conditions. The two sets of membranes are characterized by two normal pore size distributions. Membranes exhibiting a narrower gap betwee
