Study on RO membrane fouling in landfill leachate treatment
处理垃圾渗滤液的反渗透膜污染研究

Prevention and control of membrane fouling is a major factor influencing membrane performance.Study on membrane fouling and chemical cleaning was carried out by analyzing Disc-tube RO membrane treating landfill leachate for more than one year.The study results indicated that membrane fouling layer was a complex system,in which organic substances played a major role in membrane fouling,containing Al and Si colloid,as well as Ca and Fe compound.The optimum method of chemical cleaning is alkali agents followed by acid agent,because organic substances act an important role in fouling layer formation.
