Application background

Ternary precursor wastewater is usually divided into washing water, mother liquor, concentrated alkali washing solution, dilute alkali washing solution and other wastewater. The washing water and dilute alkali washing solution usually have pH = 9-11, salt concentration of 0.5% - 1%, ammonia nitrogen content of several hundred and contain a small amount of heavy metal suspension; Mother liquor and concentrated alkali washing liquor usually have high ammonia nitrogen content, high sodium sulfate content, pH = 11-13 and contain a large amount of complex nickel cobalt manganese.

Technological Process

Technical Advantages

1 The washing water and mother liquor are treated separately, and the washing water is concentrated to the greatest extent, with low operation cost;

2 Produce pure water, ammonia, sodium sulfate and NCM filter cake, with high recovery efficiency;

3 The quality of sodium sulphate is high and does not contain heavy metals;

4 Pure water and ammonia can be reused for production.
