Fluorine sodium silicate manufacturers how to do wastewater treatment - Appropriate chemical industry

fluorine sodium silicate has been widely used in industrial production, the manufacturer of sodium fluosilicate is also attaches great importance to the production of sodium fluosilicate, fluorine sodium silicate process will appear a lot of waste water, the fluorine sodium silicate factory is how to deal with the waste water?

sodium fluosilicate manufacturer for wastewater by careful analysis, it is concluded that under normal circumstances, the fluorine sodium silicate production wastewater, the mass fraction of hydrochloric acid is less than 5%, fluorine mass fraction is less than 0. 7%. These are the environmental pollution of chemical elements, fluorine sodium silicate manufacturers therefore want to deal with these elements.

sodium fluosilicate manufacturer with limestone and lime neutralization, will reduce fluorine mass fraction in the liquid phase. Here, need to be aware of is, and, in the liquid phase to produce calcium silicofluoride, when in the liquid phase ph > 1. After 9, fluoride calcium silicate hydrolysis to generate calcium fluoride, when in the process of ph from low to high fluoride calcium silicate hydrolysis rate will gradually speed up.

but due to the solubility of calcium fluoride, thus instantly formed a great degree of supersaturation, generate the settlement of solid phase so that the subsequent troubles. Therefore and fluorine sodium silicate plant waste water is divided into two sections, a ph control is controlled in 3, the degree of supersaturation of calcium fluoride in relatively small after nucleation and adequately. At the other end with the lime milk neutralization, generated by solid-phase easy separation, and the economy.

sodium fluosilicate manufacturer processing wastewater is struggling, look forward to have better ways of dealing with wastewater.
