Problems with water utilization of potassium dihydrogen phosphate MKP mother liquor
Thread Content
According to the production data, we generally produce MKP mother liquor and cannot reuse it after 6 uses. The discharge and disposal have not yet been tested. I don’t know the content of P2O5 and K2O. But one question is that if I want to make it into a liquid fertilizer, will there be a crystallization problem? And the free acid problem? Can alkaline fertilizer or ammonia be used to adjust the pH to avoid
It is definitely not possible to dispose of emissions. Not only will the cost of consumption increase, it will also affect the environment.； As for making liquid fertilizer, it is definitely possible as long as there are sales channels. Raising the pH should not cause crystallization. The solubility of dipotassium hydrogen is much greater than that of monopotassium. I have not tested it with ammonia. I don’t know whether monoammonium will precipitate.
