High Quality Anthracite Filter Media For Water Filtration
anthracite which used water filtration
We have made our Anthracite filter media using ‘Taixi’ black coal by washing, selecting, smashing, repeatedly screening, and other procedures. It does have a nice lustrousness; resists compression, has good mechanical strength and has steady chemical activity. We will offer you high-quality Black coal filter media for water filtration.
Combining anthracite with filtering sands makes it an excellent filter media for water clarification in drinking or industrial use. It is a widely used filtering media.
What is anthracite?
Black coal is a raw material for water purification as filter media. Additionally, it has features such as low ash, Sulphur, phosphorus, and high calorific power. Moreover, it exhibits several characteristics such as mass resistivity, a high percentage of lump coal, chemical activity, a high recycle rate of head coal, and remarkable mechanical strength.
What’s more, it enjoys the trait of innocuity and dissolvability in acidic, neutral, alkaline water, and more. In the manufacturing process, we transform our Anthracite filtermedia using “Taixi” anthracite through various procedures including washing, selecting, smashing, and repeatedly screening. Furthermore, this filter media possesses numerous desirable characteristics.
For instance, it exhibits pleasant lustrousness, exceptional mechanical strength, resistance to compression, durability, and consistent chemical activity. Additionally, it demonstrates remarkable separate-absorb activity. Consequently, this material can effectively absorb and eliminate color, stink, flavor, and minute organisms in water. As a result, it finds extensive applications in filtering life water, industrial water, and municipal sewage. Undoubtedly, it stands out as an excellent material for environmental protection.
