Research progress in control method of water treatment membrane fouling

The research progress of membrane fouling control method in water treatment is introduced by four aspects of solution environment, hydraulics condition, membrane property and strengthening coupling process. Former two influence membrane fouling process by changing system charge and membrane surface shear stress. Modified anti-fouling membrane could be achieved by membrane structure improvement, hydrophilic modification and membrane charge modification. The modified method can be divided into casting solution modification and membrane surface modification. Point out that the research of membrane fouling on-line control method should be focus on the preparation of high performance modifiers.
