waste water treatment sand filter,sand media filter for water treatment,Porcelain Sand Filter for water treatment,Porcelain sand
The porcelain sand filter is produced by high quality kaolin clay, binders, pore forming agent after burning in high temperature. It is new type of filtering material
with white appearance, hard, uniform particles, the developed micro porous, porosity, and good roundness.It is the upgraded product for
traditional media such as quartz sand and anthracite.
Ceramic grain filters are made of refined pottery clays added with certain modifiers,and processed of grinding,mixing,shaping and high temperature sintering. Ceramic grain filters do not contain any substances that harmful to people or environment.
