浓水反渗透膜元件化学清洗分析

反渗透膜的污染会造成系统性能的下降、组件进出口压差的升高、膜元件的更换等。对膜进行定期的清洗是保证反渗透系统的正常运行、延长膜元件使用寿命的有效途径。通过对浓水反渗透系统污染原因的解读分析，讨论了反渗透膜清洗的方法，通过对浓水反渗透系统两次化学清洗数据进行对比分析，提出浓水反渗透系统优化运行的相关措施。

Chemical Cleaning Analysis of Concentrated Water Reverse Osmosis Membrane

RO membrane fouling can cause system performance degradation, component of pressure difference between inlet and outlet, the increase of membrane components replacement. Periodic cleaning for the membrane is effective way to ensure the normal system operation and extend service life of elements of. Through analysis to the reason of concentrated reverse osmosis water system pollution, this article introduces the cleaning of reverse osmosis membrane method, and through two chemical cleaning data of dense water reverse osmosis system, it puts forward the optimal operation measures for concentrated water reverse osmosis system.
