Ultrafiltration (UF) is a membrane separation process used in a wide range of applications, such as: water/wastewater treatment, water pre-treatment for reverse osmosis, separations in food, chemical and biochemical industries. With the developement of low-pressure membranes, membrane applications, including ultrafiltration, have been growing exponentially in recent years. However, a major challenge in the application of ultrafiltration is membrane fouling by the solutes in the feed solution. Membrane fouling causes a reduction of the filtrate flux with time, and hence, a low filtration efficiency.

超滤(UF)是一种广泛应用的膜分离过程，如：水/废水处理、反渗透水的前处理、食品、化学和生化工业中的分离。随着低压膜的发展，包括超滤在内的膜应用近年来呈指数级增长。然而，超滤应用中的一个主要挑战是料液中的溶质对膜的污染。膜污染会导致滤液通量随时间的延长而降低，从而降低过滤效率。
