Anthracite is an excellent filter media for water clarification in drinking or industrial use, when used in combination with filtering sands. It is one of the most used filtering media. It is a good complement for the mixed filters, in company of sand or green manganese sand. Due to the special shape of its grains, it allows the suspended particles to be retained in the depth of the filtering bed. Compared to a sand filter, this filtering medium allows a higher flow, less pressure drop and a better and faster backwash. Physical Properties: Color: Black Bulk Density: 50 lbs./cu. ft Hardness: 3.0-3.8 (Mohs scale) Uniformity Coefficient: <1.7 Acid Solubility: <1% Caustic Solubility ((1% NaOH @ 190°F)) : <1% Apparent Specific Gravity: 1.6 gm/cc Meets AWWA Standard B100-01 Mesh Size : 0.6 x 0.8 mm , 0.85 x 0.95 mm, 1.70 x 2.05 mm Conditions For Operation: Bed depth: 24-36 inches Freeboard: 50% of bed depth (min.) Service flow rate: 5 gpm/sq. ft. Dissolved Oxygen (D.O.) content must be equal to at least 15% of the iron and 29% of the manganese content. Backwash flow rate: 18-25 gpm/sq. ft Packaging Size: 30kg(66lb) Advantages The shape of particles allows suspended particles to be retained over the depth of the filter bed It complements mixed filters very well, particularly Green and Manganese Sand filter media Allows for higher flow rate compared to sand Smaller pressure drop compared to sand Faster backwash rate compared to sand High resistance to a variety of chemicals Greater physical strength for use in industrial water purification. Prevents filtration blockage and more. Prevention of mad ball forming at the surface of the sand layer. Can easily transform from Single Media Filtration to Dual Media Filtration (sand).
