MANGANESE DIOXIDE is a natural MANGANESE ore that is selected for its capacity to attract heavy metals, such as IRON and MANGANESE, and for the co-precipitation of ARSENIC. The media will remove other contaminants such as HYDROGEN SULFIDE. MANGANESE DIOXIDE does not affect alkalinity, or the pH, of the filtered water, and does not add any extraneous species during treatment. Magna Filter Media is the North American distributor for this exceptional grade of MANGANESE DIOXIDE.
Sometimes referred to as pyrolucite, MANGANESE DIOXIDE can operate at flux rates up to 15 gpm / ft. sq., depending on the raw water quality / contaminant levels. Contaminants in the raw water (ARSENIC, IRON, MANGANESE, HYDROGEN SULFIDE, organic carbons, etc.) are first oxidized (usually with CHLORINE) and are then adsorbed onto the filter media. MANGANESE DIOXIDE is a permanent media that is backwashed with filtered water, and does not require chemical regeneration. Backwash water can be collected, and the sludge settled, resulting in a reclaim rate of approximately 99%. MANGANESE DIOXIDE can be used for potable water and bottling, brewery and soft drink manufacturing, in pressure and gravity filters.
