In drinking water treatment, activated alumina is organic pollutants in water, one of the most effective technology is removed. Despite people's awareness of water purification mechanism activated alumina it has not yet reached a consensus, but is generally considered active alumina prices, activated alumina is the removal of organic contaminants in the joint action of activated alumina adsorption and biodegradation completed, Adsorption of activated alumina so that the growth of microorganisms on its surface to get nutrients, and oxidative decomposition of microorganisms and adsorption capacity of the activated alumina has been restored, the two promote each other, stable treatment effect. Therefore, activated alumina process, adsorption and biodegradation are complementary and indispensable. Activated alumina for the limitations of existing selection methods exist, I propose a new evaluation method, the structure and quality of the chemical safety indicators were different activated alumina correlation analysis. Studies have shown that this method is well targeted activated alumina manufacturers, but offer convenient activated alumina, to make up for the shortcomings of the conventional method, with some guidance for activated alumina choice. Activated alumina is a porous high dispersion of solid materials, a large surface area, both good adsorption properties, and good pressure, abrasion and heat resistance, activated alumina, and therefore, It is widely used as effective adsorbents, catalyst carriers and various reactions of the desiccant. 1) Product grain structure, molecular formula, molecular weight of the grain structure: XP-type formula: AL2O3 molecular weight: 1022) Properties: white, spherical porous material, non-toxic, odorless, not powder, do not dissolve in water technology.
