High Quality Anthracite Filter Media For Water Filtration

 

 

What is anthracite ?

Anthracite is a raw material for water purification as filter media. Anthracite has features of low ash, Sulphur , phosphorus and high calorific power, mass resistivity , percentage of lump coal, chemical activity, recycle rate of head coal, mechanical strength as well as enjoying trait of innocuity, in dissolvableness in acidic, neutral, alkaline water and so on.

Our Anthracite filter media is made of “Taixi” anthracite by washing, chosen, smash, repeatedly screening and so on procedures. Anthracite has nice lustrousness , mechanical strength, resist compression, hard wearing and steady chemical activity. Also, Anthracite has some separate-absorb activity, which can absorb and disposal color, stink, flavor and minute organism in water, and applied to filter life water, industrial water as well as municipal sewage. Anthracite  a nice material for environment protection.
