The groundwater and drinking water defluorination equipment (defluorination filter) uses special activated alumina as defluorination adsorbent. The defluorination process is combined with acid or raw water pH adjustment and adsorption catalysis to obtain high adsorption performance for fluorine; large flow rate cyclic regeneration and rapid neutralization are used to achieve continuous defluorination process. Special defluorination materials are used as adsorbents, and the tank is made of carbon steel or fiberglass. The filter material can be reused. It is a new type of defluorination equipment different from the deionization method (electrodialyzer, reverse osmosis).
Technical advantages
1. Using special activated activated alumina as adsorbent, it has the characteristics of fast adsorption speed, large adsorption capacity, small influence by pH value, easy desorption, etc., and its performance is better than conventional activated alumina.
2. The regeneration agent replaces the traditional aluminum sulfate with sodium hydroxide, eliminating the harm to the human body caused by excessive aluminum ions in the effluent.
3. The cyclic regeneration method can shorten the traditional regeneration time to 4 hours.
4. The pH adjustment and catalytic adsorption process are used to greatly increase the adsorption capacity.
5. Solved the "caking" problem and "false fatigue" phenomenon of activated alumina.
Typical Applications
The defluorination filter is used for production (living) water treatment in industrial and mining enterprises, rural safe drinking water and other industries, and as a pretreatment equipment for ultrafiltration, nanofiltration, reverse osmosis, ion exchange, mixed bed, EDI and other equipment when the fluorine content in the raw water is high.
