Performance of an ultrafiltration membrane from a MBR which treats municipal wastewater with industrial discharges

Abstract:

This paper shows the performance of an ultrafiltration membrane from a membrane bioreactor (MBR) which treats municipal wastewater with industrial discharges. For this purpose, permeate of the ultrafiltration membranes and the mixed liquor from a pilot scale MBR have been characterized, and the fouling of the membranes has been studied through the transmembrane pressure variation, operating at a constant permeate flow rate. The presence of industrial discharges makes necessary to work at low permeate flows and to perform membrane relaxation periods to avoid excessive chemical cleanings. Despite the industrial discharges, both the membranes resistance and the effluent quality were excellent.
