摘要：

测试并分析了一、二级反渗透系统给水电导率及pH与系统透盐率和浓淡水pH之间的关系。测定了给水pH在6～8、给水电导率在400～1000μS/cm范围内的系统透盐率较低，且pH为7.5、电导率为500μS/cm的系统透盐率最低。此测试与分析为反渗透技术提供了重要的运行与设计依据。

Abstract:

The relationships of feedwater conductivity and pH value with the system salt permeability and concentrated fresh water in the first and second grade RO systems are tested and analysed. When the pH value of feedwater is 6 to 8 and the feedwater conductivityis in the range of400 to1 000 μS/cm, the systemsalt permeability is rather low. When the pH value is 7.5 and the feedwater conductivityis 500 μS/cm, the system salt permeability is the lowest. These tests and analyses provide important running and design basis for RO technique.

Key words: RO system, system salt permeability, pH value
