Media filtrante antracite di alta qualità per filtrazione dell’acqua
antracite che utilizzava la filtrazione dell’acqua
I nostri Antracite supporti filer è stato fatto del ‘Taixi’ antracite mediante lavaggio, scelto e smash, lo screening continuo e così sulle procedure. Ha una bella lucentezza; resiste alla compressione, alla buona resistenza meccanica e alla costante attività chimica. Ti offriremo media filtranti antracite di alta qualità per la filtrazione dell’acqua. L’antracite è un eccellente media filtrante per la chiarificazione dell’acqua nel bere o nell’uso industriale, quando utilizzato in combinazione con le sabbie filtranti. È tra i media filtranti più comunemente usati.
Che cos’è l’antracite?
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.
