1 Cubic Foot Bag. Clack MTM is a granular manganese dioxide filtering media used for reducing iron, manganese and hydrogen sulfide from water. Its active surface coating oxidizes and precipitates soluble iron and manganese. Hydrogen sulfide is oxidized to a sulfur. The precipitates are filtered out in the granular bed and removed by backwashing. Must be regenerated with potassium permanganate. Capacity Per Cu. Ft.: Iron (Fe+2) alone 600 grains (10,000 ppm). Manganese (Mn+2) alone 300 grains (5,000 ppm). Hydrogen Sulfide (H2S) alone 175 grains (3,000 ppm). Advantages: Broad operating range for iron reduction. Lower pressure loss through the bed with highflock holding capacity. Effective hydrogen sulfide, iron and manganese reduction. Lightweight requires lower backwash rates and reduces pumping requirements. Chlorine can be beneficial in extending filter run times. Low attrition loss for long bed life. Conditions for Operation: Water pH range: 6.2 – 8.5. Maximum water temp: 100°F/38°C. Bed Depth: 24-36 in. Freeboard: 50% of bed depth (min.) Service flow rate: 3 – 5 gpm/sq.ft., 8 – 10 gpm/sq.ft. intermittent flow possible. Backwash flow rate: 8 – 10 gpm per sq. ft. Backwash expansion rate: 20 – 40% of bed depth (min.). Regenerate dosage: 1-1/2 to 2 oz of KMnO4 by weight per cu. ft. soluble iron and manganese. Hydrogen sulfide is oxidized to a sulfur. The precipitates are filtered out in the granular bed and removed by backwashing.
