Abstract
A large number of membranes dynamically formed from polyelectrolytes on fine-grained (ca. 0.5 microns) supports or filters were tested for application in hyperfiltration of effluents from the primary and secondary stages of a municipal sewage treatment plant. The dynamic membranes were principally examined for salt rejection, organic rejection, flux, and flux decline with time. Cation-exchange membranes formed from anionic polyelectrolytes were generally superior to anion exchange membranes from polycations. Membranes formed from (unidentified) sewage constituents, while rejecting salts and organic materials, seemed inferior to separately formed dynamic cation-exchange-active membranes. (Author)
