REMOVAL OF TEXTILE DYES FROM WASTE WATER BY CERAMIC ULTRAFILTRATION MEMBRANE

The characterization of electrical surface properties of membrane materials is critical for understanding and predicting filtration performances of membranes. In this paper, electrical properties and rejection rates of dyes on TiO2/ZnAl2O4 (50/50) ceramic ultrafiltration membranes were studied. A correlation between the filtration results and the streaming potential measured through the membrane was established.
