Fouling characteristics of membranes with various molecular weight cut-off (MWCO) were investigated. Effects of molecular weights (MW) of humic acids and pre-treatment with PAC on membrane fouling were studied. It was found that hydraulic resistance caused by fouling materials is a better indicator than the percentage of flux decline to assess the fouling of membranes with various MWCO. Effects of MWCO of membranes and MW of humic acids on membrane fouling can be explained by the different types of fouling mechanisms.
