Research Abstract

Ultrasound cleaning technique was applied to remove fouling of ultrafiltration and microfiltration membranes, as peptone solution was permeated by cross-flow filtration. The ultrasound employed had 45 kHz frequency with 2.73 W/cm2 output power. For each polymeric membrane made of polysulfone, polyacrylonitrile and polyvinlidene fluoride, the cleaning experiments were carried out with three kinds of methods using sonication, water cleaning and water cleaning under sonication. It was found that water cleaning under sonication is effective methods for recovery of permeate flux. The ultrasound effect on cleaning of fouled membrane was also examined at different filtration temperatures using various peptone concentrations. It was discussed that the cleaning of fouled membrane by ultrasound association with water cleaning is a new effective method.
