Anthracite (Well-qualified)

Anthracite
stable chemical properties
high mechanical strength
essential filter in the single,double,and three-layer filter
Anthracite filter media:
Anthracite filter media is one of the best filter materals in China at present. Its prominent meric is that the chemical properties are stable and the mechanical strength is high . Anthracite filter material will not dissolve in the general acidic , netural and alkaline water. It is the essential filter materal in the single, double, and three-layer filter now.
our company products are in line with ministerial standard filter completely . It has the guarantee in the rate of percolation, using cycle and the quality of water is stable and so on . It runs not only the coal but also the level in the use of the process. It is in lion with the standard of CJ/T44-1999 tested by Chinese filter material center determination.
