Four treatment methods of nutshell activated carbon in sewage

As a preparation material for sewage treatment, nutshell activated carbon has unique advantages. Nutshell activated carbon can effectively intercept, filter, adsorb and purify in sewage treatment. In the face of different types of sewage in different industries, nutshell activated carbon can be used for stable and effective treatment.

Nutshell activated carbon has four main aspects in sewage treatment:

1. Degradation of dirt: For large molecules of impurity particles, due to their high density, they will easily sink on the surface of the husk activated carbon under the action of water, forming accumulations and forming dirt. china activated carbon manufacturer If the amount of dirt is large, the husk activated carbon filter layer needs to be processed Backwashing, the adsorption of such substances is weak, so backwashing is not difficult.

2. Adhesion to oily dirt: this type of dirt refers to grease-like substances. Because the oil is hydrophobic, it is easy to be adsorbed by the nutshell activated carbon when facing the nutshell activated carbon, thereby sticking together, and the grease around the nutshell activated carbon can also be used Adhering to some fine particles and suspended matter, these substances need to be removed in time, and it is difficult to remove them by simple means after the nut shell activated carbon adsorbs such substances.

3. Electrostatic adsorption: Molecules with different electric charges inside the shell activated carbon can adsorb positive and negative electric impurity particles in the water by the gravitational force between different electric charges, and water pressure can be used for effective removal during backwashing.

4. Diffusion: use the diffusion of impurity particles in the water flow to gradually migrate to the inside of the activated carbon pores of the husk to achieve the removal effect. The diffusion effect is not good during backwashing. Generally, cleaning with chemicals can ensure the husk The activated carbon returns to its original filtering state.https://www.coalactivatedcarbon.com
