CHARACTERIZATION OF GEL LAYER FORMED DURING ULTRAFILTRATION OF LATEX EMULSION WASTE-WATERS

The results of investigations of the ultrafiltration of latex waste wa ters, carried out with and without stirring, have been presented. The dependence of the permeate flux versus time profiles, transmembrane pr essure and latex particle concentration for three polyacrylonitrile me mbranes of differing compactness, have been worked out. The basic para meters of the gel layer formed on the membrane surface, i.e., the resi stance of the gel layer (G(g)), specific resistance (a) and mass of ge l per unit area of the membrane (m(g)/A(m)) have been calculated based on the data of ultrafiltration without stirring.
