High Quality Anthracite Filter Media For Water Filtration
anthracite which used water filtration
Our Anthracite filer media has been made of the ‘Taixi’ anthracite by washing, chosen as well as smash, continuous screening and so on procedures. It does have a nice lustrousness; resists compression, has good mechanical strength and has steady chemical activity. We will offer you high-quality anthracite filter media for water filtration. Anthracite is an excellent filter media for water clarification in drinking or industrial use when it is used in combination with the filtering sands. It is among the most commonly used filtering media.
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, choosing, smashing, 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 dispose of color, stink, flavor, and minute organisms in water, and is applied to filter life water, industrial water as well as municipal sewage. Anthracite is an excellent material for environmental protection.
