Choose high quality clay ceramic sand filter material, adding pore forming agent, solvent, the ball mill, screening, molding and calcination. Its surface is hard, internal micro porous, has a large specific surface area, high porosity, etc. Used for water treatment, with strong ability of sewage filtration cycle long, the filter head loss is small, backwash water consumption is low, is to increase water rate, improve water quality, save energy consumption of a new type of filter material. In waste water treatment and water treatment, precipitation, coagulation, commonly used methods of biological ceramic sand filter.
