Abstract Microfiltration (MF) and ultrafiltration (UF) have been used as pretreatment to reverse osmosis of biologically treated effluent in previous pilot-scale salt reduction trials at Melbourne's Western Treatment Plant. In this study, statistical correlation between the water quality parameters of turbidity, total suspended solids, dissolved organic content, total algal content, total dissolved solids, conductivity and MF and UF filterability of treated effluent from WTP (in terms of permeate volume at a final flux rate of 40 L m-2 h-1 ) was established using multiple linear regression analysis. The models developed were found to be more useful for predicting UF than MF filterability with prediction accuracy of more than 91% and more than 83%, respectively. The models would be useful for predicting the fouling propensity of the biologically treated effluent from WTP for UF, and may be useful for MF, and thus may have application to the design of membrane processes for recycling wastewater.
