HCFG series defluorination filter

1、 Overview　　

The defluorination filter uses activated alumina adsorbent for defluorination treatment. Activated alumina adsorption filtration is currently the most mature, widely used, and effective method for fluoride removal. Activated alumina is a amphoteric substance with ion exchange properties in water, with an isoelectric point of approximately pH 9.5. When the pH of water is less than 9.5, it can adsorb anions, and when the pH of water is greater than 9.5, it can adsorb cations. Therefore, in acidic solutions, activated alumina is an anion exchanger with great selectivity for fluorine.

IIApplication Fields

Fluoride removal filters are applied in the production (domestic) water treatment of industrial and mining enterprises, rural safe drinking water and other industries, as well as in the pre filtration of ultrafiltration, nanofiltration, reverse osmosis, ion exchange, mixed bed, EDI and other equipment when the fluoride content in raw water is high
