Wastewater Defluorination Equipment

Working Principle

Adsorption method refers to the process of passing fluoride-containing wastewater through porous solid adsorbents, allowing the exchange of fluoride ions with ions or groups in the adsorbent to achieve fluoride removal. In the field of fluoride wastewater treatment, it is mainly used to remove trace fluoride pollutants from water. After the fluoride-containing wastewater comes into contact with the fluoride removal filter media, dual reactions of adsorption filtration and ion exchange occur on the surface of the media. The fluoride ions in the water are adsorbed onto the media, and fluoride ions exchange with OH- ions on the media surface. The purpose of fluoride removal is achieved through this dual-effect physicochemical reaction. Media regeneration: after a period of operation, when the natural mineral media reaches adsorption and exchange saturation, it needs to be regenerated through the regeneration system. After regeneration, the media performance returns to its initial state and can be used repeatedly for a long time. The regeneration liquid can be reused after treatment in our equipment without discharge.
