Abstract

PURPOSE: To remove borofluoride (compound of boron and fluorine in waste water) without pressure and heat using methylene blue and activated charcoal.
CONSTITUTION: Borofluoride or fluorine is removed from waste water by the steps of adsorbing methylene blue in advance with activated charcoal and making the charcoal contact with waste water containing borofluoride drained from a metal treating plant of the like to thereby produce complex of borofluoride contained in the waste water and methylene blue adsorbed to the activated charcoal and adsorbing to retain the complex with the charcoal as it is. According to this method, it is easily controlled without heating nor pressurizing it.
