Abstract

PURPOSE: To remove fluorine contained in waste liquid at low running cost while producing little sludge and also while preventing CaF2 from being rendered into a state having a character of glue by adding a compound of Ca such as limestone to the liquid, forming CaF2 by passing current and removing the CaF2 thus formed.
