Activated Alumina For Waste Water
1.Activated alumina has a strong adsorption effect on fluoride ions in wastewater
2.Products soaked in water due to its high strength and high hardness will not become soft
3.It will not expand and rupture, harmless to water quality
Product Introduction
Production Introduction
Activated alumina for waste water has many capillary pores and a large surface area. It is also determined according to the polarity of the adsorbed substance. It has a strong affinity for water, oxides, alkalis, etc. It has a good adsorption and defluorination effect, and its capacity is stable. Per stere activated alumina can absorb 6400 grams of fluorine.

Product feature and application
Activated alumina is one of the inorganic chemical products widely used in the world.
Due to its porous structure,high specific surface area and unstable transition state,it has greater activity.At present,the main industrial activated alumina products are produced by rapid dewatering,which are mainly used for defluorination in drinking water or other industrial devices.Activated alumina can be continuously used for 6-8 years,when the surface appears yellow brown,the effect of fluoride removal is significantly reduced,this is caused by impurities in the water pollution,the treatment method is every half year with 3% diluted hydrochloric acid treatment, its operation method is the same as the regeneration method.
