For brine refining in Chlor-alkali industry
Without sand filter, fine filter

Jiangsu Jiuwu Hitech Co., Ltd studied and developed the application of ceramic membrane for brine refining in Chlor-alkali industry from 2005. Through more than 2 years experiment and research, the filtration technology of ceramic membrane for brine refining in Chlor-alkali industry was developed successfully and gained national patent (No.: 200610038868.3). This filtration technology has the advantages of short process, less equipments, less area, low investment, less energy and so on. Other filtration technologies can not be compared with it. The technology solves the problem about the incompatibility of organic membrane and fluffy precipitate of organics and magnesium hydroxide. So there is only one step for reaction, no prefiltration equipment, simplified process steps, and saving investment more than 35%. The operation of equipment is easy and stable. The backpulsing and cleaning are not frequent.

Only three steps:

A. Salt solution
B. Refining reaction
C. Filtration separation by ceramic membrane
