The Optimization Of Filterableness Of Suspensions Obtained By Issolving Ulexite In So2-Saturated Water

Abstract

In this study, the optimum conditions of cross-flow microfiltration of suspension obtained by dissolving ulexite at 90oC in SO2-saturated water were determined by Taguchi Method. Experimental parameters were transmembrane pressure, cross-flow rate and membrane porosity. Permeate were measured at 3.8-8.3 L.min-1 cross-flow rate and 200-400 kPa transmembrane pressure by using membranes with various pore size. Particle concentration, temperature and pH were taken constant as 22.9 g.mL-1, 30oC and 7.33, respectively. As result, optimum conditions were determined 300 kPa for transmembran pressure, 8.3 L.min-1 for cross-flow rate using cellulose acetate with 2.5 m of pore size
