摘要
超纯水系统中的反渗透膜无法长时间在原水水质硬度过大的条件下正常运转,本文就原水水质硬度大对反渗透膜的不良影响,及软水剂、防垢剂除盐法和阳树脂交换除盐法这两种软化水方法的实际效果进行了探讨和比较。经过长期实践,采用膜前树脂交换除盐法为主,各类添加剂为辅的前处理方法成功解决了这一问题。
The Reverse Osmosis membranes in ultra-pure water system can not work well in hard water. This paper discusses the harm of hard-water to Reverse Osmosis membranes and the effect of different way on softening of the water. This study presents a good method to solve this problem.
