Methods Based on the index related to the total sinomenine reserved in liquid and fouling degree of membrane,compared to other pretreatments,discuss the function of chitosan used as flocculation and the effect on membrane separation by orthogonal test.

Objective To investigate chitosan flocculating and other pretreatments of Huoxue Tongluo extract and their effects on the membrane flux and fouling degree of membrane.

Effect of operational parameters on membrane fouling in hybrid membrane bioreactor(HMBR) with suspended carriers;

Effect of extracellular polymeric substances on membrane fouling of membrane bioreactor;

Extraction and analysis of extracellular polymeric substances in membrane fouling in SMBR;

Study on RO membrane fouling in landfill leachate treatment;

Study on characteristics of membrane fouling during the ultrafiltration of natural organic matters;

Study on effect of powdered activated carbon on the fouling in a submerged membrane bioreactor;

Treatment of sewage with ceramic membrane and research for membrane pollution and cleaning;

Characteristics of membrane pollution and its cleaning in a coagulation-microfiltration combination process for water purification.;

Study on the effect of membrane pollution for hyaluronic acid broth ultrafiltration with different pre-treat method;

Besides,it also introduced the prevention methods of membrane contamination by improving the membrane self anti-pollute ability,changing mixed liquid property,optimizing operating condition and membrane washing.

The use of membranes has become one of the most sought-after techniques in separation processes, and there has been great advancement in development of membrane systems, but the fouling of membranes becomes the bottleneck limiting the wider application of membranes.
