正渗透过程膜污染及清洗方法

Membrane fouling during forward osmosis and its cleaning

正向渗透膜技术因其特有的优势越来越受到重视。在正渗透过程中,不可避免的膜污染是限制其应用的重要因素。文中综述了目前正渗透过程中膜污染的种类和特征,介绍了膜污染清洗技术的研究进展,并简要展望了正渗透清洗技术的发展方向。

Forward osmosis membrane technology is more and more attentioned because of its unique advantages. The membrane fouling inevitably in the process is an important factor to limit its application. In this paper, the characteristic and classification of membrane fouling in process of forward osmosis are summarized, the study progress of membrane fouling cleaning technology are introduced and the future directions of forward osmosis membrane cleaning technology are also briefly discussed.
