Is evaporation crystallization feasible for sodium hydroxide waste liquid? How much can be earned from the concentration? ?
As for the concentration, it depends on the solubility of the saturated solution; one can conduct an experiment to find this out
Evaporative crystallization of strong alkaline waste liquid is very difficult; how much more do you want to make? Dream on; it’s good enough if you don’t lose anything.
If the volume is large and production is on a large scale, the investment required is substantial, and the quality is very poor, so it’s hardly possible to sell it at a good price. If the volume is small, the cost-effectiveness is also very low. Anyway, apart from being used to produce sodium hypochlorite and adjust the pH value, waste alkaline solution has little practical use.
