A wastewater reclamation system using a rotating membrane UF module has been studied by adding a powdered activated carbon to a biological treatment process to remove the organic colored matter. In this system, a powdered activated carbon dosage of 50 mg/l, and retention time of 4.5 hours have been required to stably obtain a treated water with a color of less than 5 degrees. It was found that the activated sludge dewaterability could be improved by adding the powdered activated carbon and the rotating membrane UF module could operate at a set flux of 1.0 m3/m2·d for about one and half years.
