| Abstract: | The researches of membrane separation strengthened with ultrasound at home and abroad are increasing.In this paper,the theory of membrane filtration strengthened with ultrasound as well as two models is introduced.It suggests that the performance depends on the factors such as ultrasound frequency,ultrasound intensity,solution property,cross-flow velocity,temperature,pressure and the action mode of ultrasound emitter.New technologies adopted in researches such as scanning electron microscope(SEM) and sonolu... |
