Porcelain sand filter material
Ceramic filter material selection of high-quality clay, adding poreforming agent, binder, by ball grinding, screening, molding, calcination. Its surface is hard, internal porous, with a large specific surface area, high porosity characteristics. Used for water treatment with strong sewage interception capacity, long filtration cycle, filtration head loss is small, low backwash water consumption characteristics, is to increase water production, improve water quality, save energy consumption of a new filter material.
