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.

当蛋白胨溶液通过错流过滤渗透时，采用超声波清洗技术去除超滤膜和微滤膜的污垢。所采用的超声波频率为 45 kHz，输出功率为 2.73 W/cm2。对于每种由聚砜、聚丙烯腈和聚偏二氟乙烯制成的聚合物膜，采用超声处理、水清洗和超声下水清洗三种方法进行清洗实验。研究发现，超声水清洗是恢复渗透通量的有效方法。还使用不同的蛋白胨浓度在不同的过滤温度下检查了超声波对污染膜的清洁效果。讨论了超声联合水清洗对污染膜进行清洗是一种新的有效方法。
