Use KH2PO4 mother liquor to produce liquid fertilizer?
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? Is it possible to use alkaline fertilizers or ammonia to adjust the pH? Please give me some advice.
In my personal opinion, if the nutrient concentration is too low, it definitely cannot be made into liquid fertilizer, so the various nutrient contents must be measured. . . . . . . . . .
