TREATMENT OF MULTI COMPONENTS WASTEWATER BY ACTIVATED SLUDGE PROCESS WITH CERAMIC MEMBRANE AND LOW PRESSURE REVERSE OSMOSIS MEMBRANE PROCESS

Abstract

The ASMF process was applied to treatment of artificial organic wastewater or artificial incineration ash leachate. The volumetric flux values through ceramic membrane module immersed in the aeration tank were measured under different conditions of aeration and suction mode. The intermittent aeration and suction mode reduced fouling and enabled a simultaneous removal of organic carbon and nitrogen.
The LPRO process could separate not only inorganic substances but also recalcitrant substances, in a leachate pretreated by the ASMF. A new and efficient leachate treatment process might be developed by replacing a conventional process for tertiary treatment by these processes.
