What is the proper way to deal with high chloride ion concentrations in wastewater?
Thread Content
In the chlor-alkali industry, the concentration of chloride ions in wastewater is very high; what are some effective treatment methods?
This one only uses reverse osmosis for desalination, with the concentrated water being sent for distillation and crystallization.

The cost is quite high; there’s actually no good solution for water with a high chlorine content.
Reply 5# cjpsimens: Reverse osmosis is achieved using membranes.
Reply to 6# fangqiong: Polluted membrane. Not feasible
The concentrated water after reverse osmosis can be used for desalination, but the issue of water balance must be taken into account

In the past, the most effective methods for removing chloride ions were the use of anion exchange resins or reverse osmosis, but both required additional external equipment, which posed certain limitations in terms of operation and use. It is difficult to remove chloride ions chemically, as most compounds of chloride ions are highly soluble in water, making it hard to eliminate them.

The chloride content in the chlor-alkali industry is quite complex, and scaling occurs on the tube walls as a result of distillation processes. It is necessary to clean the pipes weekly, which requires a significant amount of labor, resources, and financial investment. We have carried out pilot projects for Anhui Chlor-Alkali; we can discuss this in detail on QQ: 744232858
