Product Description


The use of alumina in the catalyst is commonly referred to as "activated alumina".

Firstly, it is a porous, highly dispersible solid material with a large surface area. Its microporous surface has the characteristics required for catalysis, such as adsorption performance, surface activity, excellent thermal stability, etc., so it is widely used. 

Secondly, activated alumina balls price is competive.

Factors affecting adsorption performance

a. 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.
b. Raw water pH value: When the pH value is greater than 5, the lower the pH value, the higher the adsorption capacity of activated alumina.
c. Initial fluorine concentration of raw water: The higher the initial fluorine concentration, the larger the adsorption capacity.
d. Raw water alkalinity: The concentration of bicarbonate in raw water is high, and the adsorption capacity will decrease.
e. Chloride and sulfate ions.
f. 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.
