Fluorine removal device

Groundwater, fluoride removal of drinking water equipment (except for fluoride filter) the introduction of new technology, new technology, new equipment, using special activated alumina as fluoride adsorbent, fluoride removal process in combination with acid or water pH on Mediation and adsorption catalytic, to obtain high adsorption properties of fluorine, fluorine removal device with aluminum sulfate and hydrogen sodium hydroxide as regenerant, using a large flow of recycling, rapid neutralization. To maximize the recovery of activated alumina adsorption performance, thereby removing fluorine process continuously. Special defluoridation material as an adsorbent, the tank is made of carbon steel or glass steel production. With the concentration of 1%-2% aluminum sulfate or sodium hydroxide solution as regenerant, filter can be reused. Is different from the deionization method ( electrodialysis, reverse osmosis ) new fluoride removal equipment.

Fluoride removal equipment features:

1. Using special activated alumina adsorbent with high adsorption rate, large adsorption capacity, the pH value of the impact of small, desorption easily, the better performance than the conventional activated alumina.

2. Regeneration agent with sodium hydroxide to replace the traditional aluminum sulfate, eliminating the water in aluminum ion overproof caused harm to the human body.

3. By cyclic regeneration method, the traditional regeneration time is shortened to 4 hours to complete.

4. By adjusting the pH value of 4 and catalytic adsorptive process so that the adsorption capacity is greatly improved.

5. Quantitative continuous adding catalyst, increased the fluoride adsorption rate.

6. Had complete resolution of activated alumina" hardening" and "false fatigue " phenomenon.
