The knowledge of activated carbon in water treatment is very rich. We carefully observed the water quality of users when filling them with activated carbon and studied the workflow of activated carbon for water treatment. This project has also accumulated a lot of work experience for us. Next, we will talk about the combination and selection of water treatment filter media, activated carbon, and water treatment equipment.

Activated carbon water treatment filter material is used in water quality pretreatment systems. Activated carbon filters can adsorb residual chlorine that cannot be removed in the previous stage of filtration to prevent the subsequent reverse osmosis membrane from being oxidized and degraded. At the same time, they also adsorb small molecule organic matter and other pollutants leaked from the previous stage, and have a significant removal and adsorption effect on colloids, pigments, heavy metal ions, water odors, COD, etc. It is possible to further reduce the SDI value of RO inlet water, ensuring SDI<5 and TOC<2 Oppm.

In many high-quality residential areas in cities, we can see the presence of automatic water dispensers. As long as we put in coins, we can take our water buckets to pick up water, without having to call the water company to deliver it. It's really convenient. On this automatic water dispenser, it is indicated that the drinking water has been purified layer by layer, including activated carbon. Not all activated carbon can be used for drinking water filtration, only high-quality and pure activated carbon and coconut shell activated carbon can be used. Why does activated carbon have such miraculous effects?

The operation of activated carbon filters is accomplished through a carbon bed. The activated carbon particles that make up the carbon bed have many micropores and a huge specific surface area, and have strong physical adsorption capacity. Water passes through an activated carbon bed, and organic pollutants in the water are effectively adsorbed by activated carbon. In addition, there are some oxygen-containing pipe clusters on the non crystalline part of the surface of activated carbon, which effectively adsorb organic pollutants in the water passing through the carbon bed by activated carbon. Activated carbon filter is a commonly used water treatment equipment. As a pre-treatment for desalination systems, it can effectively ensure the service life of downstream equipment, improve effluent quality, prevent pollution, especially prevent free residual oxygen poisoning and pollution from downstream reverse osmosis membranes, ion exchange resins, etc.
