KTPL AC-KT coal based activated carbon is manufactured from selected bituminous coal and is designed for reduction of tastes, odours, dissolve organics from raw water. Activation is carefully controlled to produce exceptionally high internal surface area with optimum pore size for the adsorption of a broad range of high and low molecular weight organic contaminants. To obtain maximum efficiency of the activated carbon in the adsorption process, it is desirable to have the greatest possible surface area in the smallest practical volume and AC-KT has a great surface area of 877 square meters per gram. his results in high efficiency and greater system economy. AC-KT requires periodic backwashing to eliminate accumulated suspended matter and to re-grade the filter bed. AC-KT has replaced when the filter bed loses the capacity for reduction of taste and odor. PHYSICAL PROPERTIES: Color: Black Bulk Density: 30  lbs./cu. ft.

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 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).

Greensand KT is effective at higher operating temperatures and higher differential pressures than ordinary manganese greensand. Greensand KT is a black filter media used for removing soluble iron, manganese, hydrogen sulfide, arsenic, and radium from water supplies. The manganese dioxide coated surface of Greensand KT acts as a catalyst in the oxidation reduction reaction of iron and manganese. Systems may be designed using either vertical or horizontal pressure filters, as well as open gravity filters. Greensand KT is a proven technology for iron, manganese, arsenic, radium, and hydrogen sulfide removal. Unlike in-situ treated media, there is no need for extensive preconditioning of filter media or lengthy startup periods, during which required water quality may not be met.
