Abstract

Membrane-based remediation of oily wastewater is often accompanied by severe fouling of hydrophobic membrane surfaces by oil. One strategy for in situ membrane cleaning is to backpulse clean permeate water through the membrane periodically to temporarily reduce fouling and enhance water flux. The effect of operating variables (backpulse pressure, frequency, and duration) on the time-averaged flux in polysulfone ultrafiltration membranes used to separate oil-water emulsions was presented. Optimum strategies for backpulsing were described. Original is an abstract.
