The high salt water treatment system project for a carbon black Co., Ltd. is a representative project of zero wastewater discharge. The project uses the process of "pretreatment + membrane concentration + salt extraction" to reduce the influent COD from 60mg / L to 30mg / L and ammonia nitrogen to 5mg / L.

The overall recovery rate of the whole system is more than 84%, the purity of sodium chloride and sodium sulfate separated is more than 97% and 92%, respectively reaching the secondary standard of industrial dry salt in industrial salt and class III standard of industrial anhydrous sodium sulfate.
