反渗透系统运行存在的问题及解决方案

Problems and Solutions in Operation of Reverse Osmosis System

目前,由于水污染问题日趋严重,水质越来越差。为了满足生产要求,很多领域都已经开始使用反渗透设备,反渗透已然成为水处理领域的主导技术。然而,在反渗透处理过程中,膜污染始终是制约该技术得以广泛应用的瓶颈之一。通过分析膜污染的影响因素,研究控制污染的工艺,可以极大提高反渗透的出水水质,延长其使用寿命,降低其运行成本。

Nowadays, as water pollution is becoming increasingly serious, water quality is getting worse and worse. The reverse osmosis has become the dominant technology in water treatment area, and the reverse osmosis equipments have been widely used in many fields in order to meet the production requirements. However, membrane fouling has always been one of the bottlenecks that restrict the wide promotion of the technology of reverse osmosis process. Through the analysis of membrane fouling factors and study on pollution control technology, we could greatly improve the effluent quality, extend the life of reverse osmosis and reduce its operating costs.
