Abstract：

In this study, bovine serum protein (BSA) was selected to represent the typical organic foulants of ultrafiltration membranes. Before and after pre-ozonation, the fouling layer structure, the adsorption behavior of foulants onto membrane surface and the interaction force of foulants at membrane surface were investigated. All these were combined with the results of macro membrane fouling behavior to unravel the influence mechanism of pre-ozonation on the protein fouling of ultrafiltration membranes with different pore size.
