A new ultrasonic cleaning model for predicting the flux recovery of the UF membrane fouled with humic acid

Ultrasonic cleaning is an alternative promising method to control the membrane fouling. At present, the urgent task of further promoting its application is to establish a model to predict the instantaneous membrane flux. In this study, a new model was proposed by considering the power intensity and...

Description
Summary:Ultrasonic cleaning is an alternative promising method to control the membrane fouling. At present, the urgent task of further promoting its application is to establish a model to predict the instantaneous membrane flux. In this study, a new model was proposed by considering the power intensity and temperature, and the ultrasonic cleaning mechanism was revealed with ultrasonic cavitation theory and extended Derjaguin–Landau–Verwey–Overbeek (XDLVO) theory. Results showed that the predictions of the model were in good agreement with the experimental data (σ
