columnar activated carbon filtration and adsorption principle

columnar activated carbon is made of activated carbon particles. One way to make columnar activated carbon is to add activated carbon granules to a plastic tube and heat it to form a dense rotational molded body. The columnar activated carbon produced by this method has a small surface area and poor filtration effect.

Activated carbon is a common filter material, and columnar activated carbon is a form of activated carbon that is often used to filter and absorb pollutants in water and air. This article will start with the production method of columnar activated carbon and introduce the filtration and adsorption principles and applications of columnar activated carbon.

How to make columnar activated carbon

columnar activated carbon is made of activated carbon particles. One way to make columnar activated carbon is to add activated carbon granules to a plastic tube and heat it to form a dense rotational molded body. The columnar activated carbon produced by this method has a small surface area and poor filtration effect. Another method is to add activated carbon particles to a certain binder and then dry them at high temperature to combine the binder and activated carbon particles to form a good filtration effect.

Filtration principle of columnar activated carbon The filtration principle of columnar activated carbon is physical adsorption. Physical adsorption refers to the adsorption of gas or liquid molecules to the surface of an adsorbent through intermolecular attraction. The manufacturing method of columnar activated carbon results in the formation of a large number of micropores and mesopores, which can effectively absorb various excess impurities. Since the gaps between columnar activated carbon particles are very smallthese impurities can hardly escape through these gaps, thus effectively filtering.

Adsorption principle of columnar activated carbon

The adsorption principle of columnar activated carbon is chemical adsorption. Chemical adsorption means that adsorbents are bonded together through chemical bonds. Due to its large surface area and pore structure, columnar activated carbon has high efficiency in adsorption. Various organic pollutants such as organic matter, chlorine, benzene, etc. are all adsorbed by columnar activated carbon and effectively removed.  

Application of columnar activated carbon

Pillar activated carbon is widely used in the fields of air and water purification. In the field of water treatment and purification, activated carbon is often used to remove suspended solids, organic pollutants, odors and colors. For example, some drinking water plants use columnar activated carbon to remove chlorine dioxide and chloride ions from water. In the field of air purification, columnar activated carbon is usually used to filter odors and harmful gases in the air. Pillar activated carbon is usually used in car air purifiers to filter harmful gases such as nitrogen dioxide and formaldehyde to purify the air.

In conclusion

The production method and filtration and adsorption principles of columnar activated carbon are introduced in detail. Activated carbon is widely used in the fields of water purification and air purification due to its advantages of good full filtration and efficient adsorption. Paying attention to the theoretical research of columnar activated carbon, improving production methods and enhancing adsorption and filtration effects will effectively promote the development of columnar activated carbon applications.
