The permeate flux of the ceramic membrane in the microfiltration of TiO2 suspension was affected significantly by the solution environment including pH and Ionic strengths. The steady-state flux increased with increasing ionic strength in the presence of electrolytes, NaCl and Na2SO4, and decreasing

Taking into account the presented results, it can be stated that ultrafiltration — low pressure membrane process — is suitable for concentration of highly polluted effluents containing detergents. The high separation efficiency of anionic surfactant from model solutions as well as from detergent was

If the feed flow is sufficiently higher than the permeate flow rate, membrane overlapping, which

This work was aimed at evaluating adsorption of water molecules onto membrane surfaces modified by sulphonamide derivates. Controlling interfacial forces at the membrane-feed interface were assessed by combining experimental and theoretical studies. The phenomena experimentally observed were also in

In the present work the permeability and separation and properties of homogeneous polymeric films and composite polymeric membranes based on PTMSP for removing hydrocarbons from gas mixtures were studied. The dependence of permeability for single N2, CH4, n-C4H10 on feed pressure was obtained. The b
