What are the main factors affecting the adsorption of activated alumina products by Tieling Zhengda?

Alumina is a white spherical porous particle with uniform particle size, smooth surface, high mechanical strength, strong hygroscopicity, no swelling and no cracking after being absorbed. It is non-toxic, odorless, insoluble in water and ethanol, and has strong fluorine. Adsorption, mainly used in the defluoridation of drinking water in high-fluorine areas, the main factors affecting the adsorption of activated alumina products

The main factors affecting the adsorption properties of activated alumina:
(1) Particle size: The smaller the particle size, the higher the adsorption capacity, but the smaller the particle size, the lower the particle strength, which affects its service life.
(2) PH value of raw water: When the pH value is greater than 5, the lower the pH value, the higher the adsorption capacity of activated alumina.
(3) Initial fluorine concentration of raw water: The higher the initial fluorine concentration, the larger the adsorption capacity.
(4) Raw water alkalinity: The concentration of bicarbonate in raw water is high, and the adsorption capacity will decrease.
(4) Chloride and sulfate ions.
(5) Effect of arsenic: Activated alumina has an adsorption effect on arsenic in water. The accumulation of arsenic on activated alumina causes a decrease in the adsorption capacity of fluoride ions, and it is difficult to elute arsenic ions during regeneration.

Pellet Activated Carbon,depend on it's shape,also can be named as Pellet Carbon,Cylinder Carbon,Column Carbon, is Huahui Company's first major series of products. Diameter adjustable changes between 0.9-9.0mm;

Pellet activated carbon , which is the first main product of HuaHui Company, can be supplied from the range of 0.9mm till 9.0mm in diameter according to clients` requirement. This kind of carbon is made of high standard Taixi anthracite and coal, processed through grinding, mixture, extrusion, carbonization and steam activation etc. Due to the high mechanical hardness, highly developed pore structure and huge specific surface area, it can be widely used in both of gas-phase and fluid-phase purification and adsorption, catalyst carrier, poison and security protection.
