Tertiary Filtration with Ultrafiltration Membranes in Municipal Wastewater Treatment Plants

Abstract

During the operation of tertiary filtration stages in a dead-end-mode, retentate concentrate and rinsing water from membrane cleaning accrue naturally. Work on process solutions for these process waters with no additional particle loads for the tertiary membrane filtration stage and no further hydraulic loads is obviously necessary. A process engineering concept for the treatment of retentate volume flows by a combination of flotation technology, secondary filtration and centrifuge technology allows for a hydraulic isolation of the tertiary membrane filtration stage from the biological wastewater treatment.
