Primary brine purification system

Primary brine purification system

Raw salt contains inorganic impurities such as calcium ion, magnesium ion, sulfate and also bacterium, algae and mechanical impurities.Those impurities, if not removed, will enter brine system and damage ion-exchange membrane resulting in decreased electrolysis efficiency and shortened life-time of membrane.In order to meet the requirement of brine qualification, impurities will be removed in primary brine purification process and secondary brine purification process.

Range of Application

Compared to the traditional organic membrane process, we recommend clients to opt for the inorganic ceramic membranes process (CMS) due to its advantages of streamlined process flow, reduced footprint, and cost-effectiveness.


A complete CMS membrane filtration system includes ceramic membrane elements, membrane modules, pumps (circulating pump, feed pump, CIP pump, etc.), valves, instruments (flow, pressure, temperature, liquid level, etc.), and auxiliary equipment (heat exchange Filters, pre-filter,back flushing systems, etc.), control systems (MCC cabinet, program cabinet, PLC, inverters, etc.), frames, and some supporting storage tanks and public works.


CMS membrane filtration system can be designed as manual control, semi-automatic control, PLC & DCS fully automatic control. BPC has many years of project experience and a professional team. It can customize personalized control systems according to different requirements of users, and integrate them into the host control unit of users through network protocols to achieve remote monitoring and control.
