Anthracite filter media is used high quality anthracite as raw material, which has to be selected, crushed and twice screened. Appears well gloss and nearly spherical, with the features of high mechanical strength, compression performance, wear resistance and large specific surface area.It can not be dissolved in alkaline and acidic water ,and can be relatively stable in water treatment of chemicals. All kinds of indicators can meet users requirements, the implementation of the standards: “The Chinese people Construction of anthracite filter media used in water treatment standards.” Technical parameters: Analysis project Data Analysis project Data Carbon Content(C) min85% Hardness 3-3.75 Sulphur(S) 0.05% Ash Content max2% Copper(Cu) 0.025% Specific Gravity 1.4-1.6 Lead (Pb) 0.045% Bulk Density 0.947T/m3 Zinc(Zn) 0.04% broken rate max0.58 Acid Solubility max2% Attrition Loss max0.53 Porosity 47-52% Uniformity Coefficient K80 1.8-2.0
