Quartz sand filters utilize quartz sand as the filtering medium. The filter material has the remarkable advantages of high strength, long life, large processing flow and stable and reliable water quality. The function of quartz sand is mainly to remove suspended solids, colloid, silt and rust in water. The upper part of the activated carbon filter is provided with a water inlet device, and the lower part is provided with a drainage device. When running, the water enters through the upper part, flows through the activated carbon filter layer and flows out from the bottom. Using the surface of the activated carbon has a large amount of functional groups such as hydroxyl, the various properties of the material can be chemical adsorption, eliminate peculiar smell, organic matter in water, colloid, iron and residual chlorine, etc., at the same time reduces the water turbidity, chromaticity, make the water clear and transparent, to reduce the follow-up system (reverse osmosis, ultrafiltration, ion exchanger) pollution.
