1. Water Quality

The chloride ion content in the extraction wash water is as high as 20-30g/L, and it is 3-4g/L under normal circumstances, which seriously exceed the emission standard.

 

2. Process Principle

The bipolar electrodialysis membrane combination recycling process is used. After treatment, there is less than or equal to 10mg/L of chloride ion content, less than or equal to 1mg/L of fluoride ion content and less than or equal to 1mg/L of calcium ion content in the reuse water.
