Description

Technical Field

[0001] The utility model relates to the technical field of filters, and particularly relates to an activated carbon filter. Background Art

[0002] An activated carbon filter uses activated carbon particles to further remove residual fluorine, organic matter, suspended impurities in the water discharged from a mechanical filter, providing good conditions for subsequent reverse osmosis treatment. The activated carbon filter mainly uses activated carbon organic flocculants with high carbon content, large molecular weight, and large specific surface area to physically adsorb impurities in the water to meet the water quality requirements. Over time, the intercepts in the pores and between the particles of the activated carbon gradually increase, causing the pressure difference before and after the filter to rise accordingly until it fails.

[0003] Under normal circumstances, according to the pressure difference before and after the filter, reverse water flow is used to backwash the filter media, so that most of the intercepts adsorbed in the pores of the activated carbon are stripped and carried away by the water flow, and the adsorption function can be restored. By using reverse water inlet, the sand filter layer in the filter is loosened, so that the intercepts adhered to the surface of the filter media can be stripped and carried away by the backwash water flow, which is beneficial to removing sediment, suspended matter, etc. in the filter layer and preventing the filter media from caking, enabling it to fully restore the sewage interception and xenon removal capabilities, thus achieving the purpose of cleaning.
