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. MTM® consists of a lightweight granular core with a coating of manganese dioxide. The coating provides an example of contact filtration where the media itself provides the oxidizing potential. This allows for a much broader range of operation than many other iron removal media. A pH level as low as 6.2 can be treated. Dissolved oxygen is not essential. The media’s lightweight reduces backwash water requirements. When the oxidizing power of MTM® is reduced, the bed has to be regenerated with a weak solution of potassium permanganate (KmnO4), thus restoring its oxidizing capacity. A regenerating solution of 1-1/2 to 2 ounces (dry weight) of potassium permanganate per cubic foot is sufficient for normal regeneration. Upon start-up a new bed should be backwashed and caution taken to insure that the lightweight media is not backwashed to drain. A new bed should be regenerated the evening of installation. Operating the filter after its oxidizing capacity is exhausted will reduce its service life and may cause staining. MTM® requires either intermittent or continuous regeneration to maintain its oxidizing capacity. A solution of potassium permanganate (or chlorine then potassium permanganate) can be pre-fed to maintain capacity. In the latter case, the manganese dioxide coating acts as a catalyst to enhance the oxidation reaction and as a buffer to reduce any excess potassium permanganate concentration and prevent it from entering the service lines.

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 • Lower shipping cost Conditions for Operation: Water pH range ........6.2 – 8.5 Maximum water temp ......100°F/38°C Freeboard ...50% of bed depth (min.)
