Abstract
One of the main problems of membrane separation processes is the occurrence of the fouling and concentration polarization that cause by sedimentation on membrane surface and adsorption into the pores of the membrane particles. Membrane fouling during separation process reduced the efficiency and caused an increase in the operation cost and in the other hand the occurrence of the membrane fouling is inevitable in the membrane process, so various methods were used for the membrane recovery. On the other hand the costs related to washing such as cleaning chemicals, frequent stops of the separation operation for cleaning and etc. should be considered. All these factors cuased reduction in the production time and finnaly create the economic problems. So, understanding and knowing the effective factors that affect the fouling mechanism in order to increase the efficiency of separation and reduce the cost of washing and cleaning is necessary.
