Abstract
AbstractThe effects of casting solution composition and evaporation period on the performance of resulting porous cellulose acetate membranes have been studied, and the results are discussed in terms of casting solution structure, solvent evaporation rate during film formation, and the film shrinkage temperature profile. The development of Batch 316‐type porous cellulose acetate membranes is reported. At 90% level of solute separation and feed flow conditions corresponding to a mass transfer coefficient of 45 × 10−4 cm/sec, the productivities of the above membranes are 21.5 gallons/day/ft2 at 250 psig using 3500 ppm of NaCl in the feed, and 53.9 gallons/day/ft2 at 600 psig using 5000 ppm of NaCl in the feed.
