Abstract

Membrane filtration method has been used for various industries to remove solids and solutes from a liquid. However, the removed materials cause membrane fouling that decrease in membrane performances by pore plugging. Microbubble cleaning is expected to be a chemical free method for recovery of membrane performances. In this study, fouled membranes prepared by filtering activated sludge or yeast suspensions were used for microbubble cleaning experiments. The effects of fouling conditions and cleaning conditions on performance recovery were evaluated.
