Diffusion dialysis and electrodialysis combined technology

Product Description

Through the joint application of diffusion dialysis and electrodialysis, the production of raw materials can be fully utilized, the output of waste water can be reduced, and the sustainable water can be realized through reuse.

Step1

The extraction mother liquor (containing 10% hydrochloric acid) enters the diffusion dialysis system for the separation of hydrochloric acid and organic acid after removing solid impurities through a security filter;

Step2

Recovered hydrochloric acid with a high concentration of hydrochloric acid and almost no organic acid is reused;

Step3

The obtained hydrochloric acid concentration is less than 2% and the residual liquid containing high organic acid enters into the electrodialysis system for the deep separation and recovery of hydrochloric acid, and the residual liquid containing high organic acid enters into the electrodialysis system;

Step4

Concentrated water with a hydrochloric acid concentration of less than 0.1% and a high organic acid concentration is used in the product crystallization process.
