cze Zeolite Additives in Cross-Flow Microfiltration - Sorptive Capacity This contribution deals with the study of process combining both cross-flow microfiltration and ionic exchange on zeolites added to the feed stream. The batch experiments for sorptive capacity determination were performed for several initial concentrations of the CaCl2. Both the concentrations of Ca2+ ions in the feed and in the filtrate were determined by complexometric titration. All experiments were performed under isothermal conditions and then the sorption isotherm was estimated. The next experiments dealt with sorption measurements at cross-flow microfiltration of hard water with zeolite addition. In this time, the concentration of Ca2+ ions in the permeate was determined continuously. From these experimental data the dynamic sorptive capacity of zeolite was calculated. mikrofiltrace;zeolity;kombinované membránové procesy;sorpční kapacita;Ca2+ ionty
