Activated alumina defluoride filters out healthy water

Now people are paying more and more attention to healthy life, especially the water that people rely on for survival. With the emergence of activated alumina defluoridation agents, people start to drink healthy water. So what are the characteristics of activated alumina defluoridation agents?

The characteristics of activated alumina defluoridation agent are: large capacity for defluorination, high strength, odorless, good physical properties, no swelling, no rupture, completely reliable use, no softening when soaked in water, easy to regenerate, and long life. The water purified by the fluoride removal agent can meet the prescribed drinking water sanitation standards, and the fluoride removal effect is remarkable.

Introduction of activated alumina

High-performance modern water-purifying activated alumina can bring the following benefits in the batching of amorphous refractories: improve the density, fluidity and strength of the green body, increase the production of secondary mullite, etc., and reduce the amount of water added and porosity. In addition, activated alumina can also be used as adsorbent and desiccant, with large water absorption, fast drying speed, regeneration (400-500K baking) and water absorption without swelling, cracking and deformation.

       Activated alumina appearance

Modern water purification activated alumina is white spherical porous particles with uniform particle size, smooth surface, high mechanical strength, strong hygroscopicity, no swelling or cracking after water absorption, non-toxic, odorless, insoluble in water, ethanol, fluorine It has strong adsorption and is mainly used for defluorination of drinking water in high fluoride areas.

Modern water purification activated alumina has selective adsorption ability for gas, water vapor and moisture in some liquids. After the adsorption is saturated, it can be heated at about 175-315 ° C to remove water for recovery and regeneration. Adsorption and recovery regeneration can be performed multiple times. In addition to being used as a desiccant, it can also absorb the vapor of lubricating oil from polluted oxygen, hydrogen, carbon dioxide, natural gas, etc. And can be used as catalyst and catalyst carrier and chromatographic analysis carrier.
