Chint New Energy Technology Wastewater Deep Fluoride Removal Project

Project overview:Chint Xinneng Technology’s wastewater deep fluoride removal project treats fluoride-containing wastewater treated by Chint Xinneng Company.

Project content:Our company is responsible for providing a set of deep fluoride removal equipment. The incoming water is fluoride-containing wastewater treated by Chint New Energy Company. The fluoride in this wastewater mainly comes from the cleaning water produced by using hydrofluoric acid to clean materials during the semiconductor process production. This part of the water is generally defluorinated by calcium method chemical precipitation, which can reduce the fluoride in the wastewater to <8mg/L. According to the requirements of the local environmental protection department, the fluoride content of the factory water must be 1-3mg/L.

Processing water volume:8000 tons/day

Raw water quality:F-：5-7mg/L

Product water quality:F-：1-3mg/L
