Feature specification: ceramic grain filters Ceramic grain filters are made of refined pottery clays added with certain modifiers, and processed of grinding, mixing, shaping and high temperature ***** do not contain any substances that harmful to people or ***** are hard and rough in surface, porous inside the structure, and have the advantages of high mechanical strength, large specific surface area and porosity.When used in water treatment, they behave a activated surface property, a great amount of pollutant entrapment, less water head loss in the filter bed, lower consumption of back-flush water, stable in chemical and gbiologic property, and long service ***** grain filters is a new and efficient filter material to increase the water yield, upgrade the water quality, and save chemicals and energy. Exterior : Spherical surface , color brown, and porous Diameter: 0.***2 mm Bulk density: 2.*6 g/cm3 Porosity: *5 % Broken and wear rate: 1.*2 % Non-uniform coefficient: K*0=1.*4 % Uniformity coefficient: K*0=1.*7 % Hydrochloric acid soluble rate: 2.*3 % Sodium hydroxide soluble rate: 1.*0 %
