Activated alumina for water treatment


Activated alumina plays a great role in daily life and industry. Now we will introduce the function of activated alumina as a fluoride removal agent. Activated alumina fluoride removal agent, white spherical porous particles, uniform particle size, smooth surface, high mechanical strength, strong hygroscopicity, does not swell or crack after absorbing water, and maintain the original state. The product is non-toxic, tasteless, odorless, insoluble in water and organic Solution. The particle size is generally 1-3mm, 2-4mm, 3-5mm. It has a larger contact area with water when in use. The specific surface index is as high as 300m2/g or more. The number of micropores is huge, which can ensure the Strong adsorption capacity and high fluoride removal capacity can effectively remove free chlorine and certain heavy metals (such as Sb, Sn, Sr, etc.) harmful substances in the water. Activated alumina used as a fluoride removal agent has a life of at least 6 years. If the sphere appears yellowish-brown, it means that the fluorine removal effect has begun to decrease, and it needs to be treated with dilute hydrochloric acid. 
Activated alumina from Jiangxi OIM Chemical is used as a defluorinating agent for high-fluorine water and is a molecular adsorbent with a large specific surface area. When the pH and alkalinity of the raw water is low, the fluoride removal capacity is higher, greater than 4.0mg/g, and it can also be used to remove arsenic from drinking water. It has the advantages of high efficiency, low cost, simple operation and no secondary pollution and damage to the river ecological environment. Activated alumina has a strong adsorption effect and is extremely thermally stable. In addition to being used as a catalyst, it can be used as a desiccant for gases and liquids, an adsorbent for gas purification, a defluorinating agent for drinking water, and the color and odor of industrial sewage. Eliminators are also very good choices.
Activated alumina is widely used and is a harmless adsorbent. If need, we will provide the most affordable price and stable quality assurance.
