The shale ceramsite filters is one kind of new biomembrane carrier padding which our company develops. It is formed precisely from shale or clay, by increasing active ingredient high temperature calcine. It has good physics, chemistry and hydraulic characteristic, with large surface area, high porosity, strong adsorption interception capability. Its surface assumes multi-pore, multi-edges and corners, rough ,easy-linked membrane, and certain mechanical strength, is one kind of ideal microorganism carrier.
