Deep removal of fluoride from tungsten smelting wastewater by combined chemical coagulation-electrocoagulation treatment: From laboratory test to pilot test

Degradation of fluoride in groundwater by electrochemical fixed bed system with bauxite: performance and synergistic catalytic mechanism

“…13 The electrochemical method remains the preferred approach due to its simplicity of operation, and high removal efficiency. 14,15 Iron and aluminum are commonly used electrode plates in electrochemistry. 16 The abundant aggregation of metal hydroxides, also known as the “web catching and sweeping” method, is used to remove fluoride in water.…”

Study on the effect of an ultrasound assisted reaction on the crystallization properties of recovered cryolite

“… 26 The most common method is to treat industrial fluoride containing wastewater by adding bleaching powder, ultimately generate calcium fluoride precipitation to remove fluoride ions. 27 However, the chemical treatment process produces a large amount of waste residue, which is difficult to precipitate, and the value of the recovered products is low.…”
