Working principle of activated carbon filter tank
- Apr 08, 2018 -

Activated carbon filter tank in the process of production will generally use stainless steel 304 material, carbon steel material, mainly because activated carbon adsorption of CL and other oxidants in water, metal ions, microporous bacteria and chemical substances, the tank Corrosion, so generally activated carbon filter should be lined with plastic anti-corrosion.

Working principle of activated carbon filter tank

Activated carbon filter tank in the operation is mainly the use of granular activated carbon to further remove the remaining residual chlorine, organic matter, suspended matter impurities in the mechanical filter effluent to provide good conditions for the subsequent reverse osmosis treatment.

Activated carbon filter tank is mainly to use an activated carbon organic floc containing high carbon content, large molecular weight, and large specific surface area to physically adsorb impurities in water to meet the water quality requirements. At the same time, chlorine is adsorbed on the surface of activated carbon (hypochlorous acid). A chemical reaction occurs on the surface of the carbon, which is reduced to chloride ions, thereby effectively removing chlorine, ensuring that the amount of residual chlorine in the effluent is less than 0.1 ppm, which satisfies the operating conditions of the RO membrane.

Activated carbon canisters are mainly made of carbon beds during the work process. The activated carbon particles that make up the carbon bed have a very large number of micropores and a large specific surface area, and have a strong physical adsorption capacity. Water passes through the carbon bed and the organic pollutants in the water are effectively adsorbed by the activated carbon. In addition, there are some oxygen-containing functional groups on the non-crystalline part of the activated carbon surface, so that the organic pollutants in the water passing through the carbon bed are effectively adsorbed by the activated carbon.
