China

 By enjoying excellent reputation in China and oversea, the “Taixi” anthracite is the ideal raw materials for water purification filter media. It 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, indissolvableness in acidic, neutral, alkaline water and so on.

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