JGAC series granular activated carbon cartridge adopts natural fruit shell activated carbon, coconut shell activated carbon or high quality coal activated carbon as raw material and fills in the plastic filter shell dissolver without adding any chemical additives, and a multi-layer microfiber non-woven layer is installed at the upper and lower entrance of the container to prevent the release of carbon powder. As the liquid flows from the bottom to the top, the contact time between the liquid and the activated carbon particle layer is long, which can effectively adsorb residual chlorine, volatile organic substances, pesticides, organic solvents, pesticide residues and organic solvents.
