Fluorine sodium silicate factory and waste water processing - from the mother liquor Appropriate chemical industry

fluorine sodium silicate is a white powder crystal, stimulating has widely used in industry, is the most consumable building, building materials industry fluorosilicate varieties.

sodium fluosilicate manufacturer production time is to use sodium sulfate as raw materials, mother liquor is dilute sulphuric acid, can better utilization of mother liquor, if fluorine sodium silicate manufacturers are using sodium chloride, mother liquor is diluted hydrochloric acid, then will to corrosion of equipment, the use of problems will have great difficulty. Using sodium sulfate as raw materials, can be a solution to return to the extraction of phosphoric acid device, however, the cost will be higher than using sodium chloride many sodium sulfate, sodium fluosilicate manufacturer in accordance with the cost budget will take into consideration the selection of mother liquor.

sodium fluosilicate manufacturers in the production of sodium fluosilicate will produce a lot of waste water in the process, how to deal with the waste water, also has become an important research topic of fluorine sodium silicate manufacturer. Fluorine sodium silicate production wastewater, general hydrochloric acid mass fraction is less than 0. 5%, fluorine mass fraction is less than 0. 7%. Fluorine sodium silicate manufacturer in wastewater adding limestone to neutralize, but note that neutralization, calcium silicate, generate fluorine at low ph, calcium fluoride. In general, fluorine sodium silicate manufacturer and divided into two parts, general control ph around 3, the calcium fluoride in a relatively small degree of supersaturation of nucleation and then continue to neutralize after adding lime milk neutralization, generate solid easy separation, and low cost.

sodium fluosilicate manufacturer is considering the environmental and economic benefits, to improve the device, the waste water processing, now has achieved considerable effect.
