Abstract

Membrane fouling control is one of the key factors affecting the applicability and profitability of a membrane system. In this study, the effects of membrane surface roughness, hydrophilicity and charge on the membrane performance are discussed. New surface characterization techniques are introduced. Studies on interfacial interactions between foulants and membranes are reviewed. The effects of particle aggregation, adsorption of colloids onto particles and deformation of colloidal molecules on the fouling formation are analyzed. Finally, the theory and method of application-oriented membrane surface design are proposed. The studies on membrane fouling control are from the adjustment of operating parameters to surface and interface control, which play an increasingly important role in membrane performance improvement and industrial applications.
