Abstract：

Membrane flux determines both running stability and capital investment of a water treatment engineering using ultrafiltration. Hence, design flux is one of the most important parameters for an ultrafiltration system. On a basis of membrane technology developments and membrane cost decreasing, lower fluxes can gradually become acceptable in drinking water treatment field. However, although there are various low flux concepts used for membrane fouling control, a clear definition of low flux for ultrafiltration membranes has not been properly developed yet. In this work, the filtration tests of surface water and coagulation-sedimentation effluent were performed under both threshold and limiting fluxes. Both water purification performance and fouling developments were compared. The results indicated that the stable filtration of the tested water samples could be obtained only under the limiting flux (5.0 L/m2h). Hence, the limiting flux could be regarded as a possible resolution for membrane fouling control and stable operation of a ultrafiltration system.
