The reuse of treated wastewater to augment natural drinking water supplies is receiving serious consideration. Treatment of secondary and tertiary effluent by membrane filtration was investigated by assessing nanofiltration (NF) membrane and ultrafiltration (UF) membranes in bench-scale experiments. It was found that secondary and tertiary effluent contained high concentration of effluent organic matter (EfOM), contributing EfOM-related fouling. Flux decline and EfOM rejection tests were evaluated, using a dead-end stirred cell filtration unit. Surface charge and molecular weight cut-off (MWCO) of membranes were significant factors in membrane performance including permeability and EfOM-rejection.

Effects of coagulation/sedimentation as a pre-treatment on the dead-end ultrafiltration (UF) membrane process were studied in terms of membrane fouling and removal efficiency of natural dissolved organic matter, using Chitose River water. Two types of experiment were carried out. One was a bench scale membrane filtration with jar-test and the other was membrane filtration pilot plant combined with the Jet Mixed Separator (JMS) as a pre-coagulation/sedimentation unit. In the bench scale experiment, the effects of coagulant dosage, pH and membrane operating pressure on the membrane fouling and removal efficiency of natural dissolved organic matter were investigated. In the pilot plant experiment, we also investigated the effect of pre-coagulation/sedimentation on the membrane fouling and the removal efficiency of natural dissolved organic matter. Coagulation/sedimentation prior to membrane filtration process controlled the membrane fouling and increased the removal efficiency of natural dissolved organic matter.

The removal of dissolved organic matter (DOM) during municipal solid waste leachate treatment in a membrane bioreactor (MBR) was investigated. The MBR was operated with fouled and cleaned membranes, at a time. DOM, mixed liquor, and effluent were characterized by fractionation and fluorescence excitation–emission matrix (EEM) spectroscopy. Results showed DOM removals of 82% during the MBR operation with the fouled membrane. The DOM characterization indicated that most of the hydrophilic compounds and protein-like substances could be significantly removed by microbial activities in the treatment processes. Furthermore partial removal or transformation of organic substances was observed during membrane filtration. The fouled membrane improved DOM rejection by only about 2% when compared to the cleaned membrane, which demonstrated the significance of irreversible foulants on DOM rejection. There were insignificant differences in DOM fractionation and EEM fluorescence spectra between water samples filtered through the fouled and cleaned membranes.
