The antifouling properties of PVA/PVAm modified polyester membrane

摘要

Membrane separation technology has both advantages, such as low energy consumption and good separation performance, no secondary pollution and simple operation and disadvantages such as membrane fouling which is restricting the wide use of membrane separation, especially in wastewater /water treatment. Membrane fouling increases transmembrane pressure and/or decrease the permeate flux, and increase the frequency of membrane cleaning and the membrane module replacement. In order to reduce membrane fouling, the hydrophilic membrane modification has been proved effective.
