Coconut shell activated carbon has good adsorption properties and the pore structure is very developed. The filter material is immersed in water, and the large amount of air adsorbed by the developed pore size is gradually replaced by water molecules, resulting in a large number of bubbles.


This phenomenon is normal and will disappear after 10-15 seconds. Compared with powdered activated carbon, granular activated carbon has a larger particle size, so the surface morphology is smaller. So the diffusion of the adsorbent is an important factor.


So these carbons are the choice for all gas and vapor adsorbents because they diffuse faster. Carbon particles are used for water treatment, deodorization and separation of the components of the flow system.


Chemically activated activated carbon: first impregnated with chemicals, such as phosphoric acid or potassium hydroxide, sodium hydroxide or zinc chloride salt, and then carbonized at 450-900°C. coconut shell charcoal The carbonization/activation process is considered to proceed simultaneously with the chemical activation.


In some cases, this technology may cause problems, for example, traces of zinc residues may remain in subsequent products. But the chemical activation of activated carbon is better than physical activation, because the activation material requires a lower temperature and a shorter time.


Abrasion resistance is an important indicator to measure the abrasion resistance of activated carbon. This is an important index for coconut shell activated carbon to maintain physical integrity and resist friction such as backwashing. The hardness of activated carbon varies greatly depending on the raw material and activity


Coconut shell activated carbon is used for water treatment, which can adsorb most organic matter. Most organic substances are adsorbed on the surface of coconut shell activated carbon, which can significantly reduce the COD value of the water. When organic pollution becomes the main hazard, activated carbon becomes a protective umbrella for various unknown organic pollution in water treatment.


Activated carbon removes residual chlorine in water. Through oxidation-reduction reaction, activated carbon removes residual chlorine in water. Practical applications have shown that after coconut shell activated carbon is saturated with adsorption, the COD decline is not large. As long as the water flow rate is controlled, the activated carbon can be removed. Chlorine still has a good effect.
