STAND ALONE AUTOMATIC GREENSAND FILTER REMOVES IRON, MANGANESE, AND HYDROGEN SULFIDE FROM THE WATER. 14x65 Tank (3.5 cubic foot) Mineral Tank Size(size inches): 14x65 Inlet\Outlet: 1" Service Flow Rate: 7 gpm Back Flow Rate: 10 gpm Iron: 24,000 Manganese: 12,000 Sulfur: 7,000 Refill Order Number: AIF-3.5 Refill Description: This line of Iron Filters contains fine greensand grains which are coated with manganese dioxide. Iron, manganese, and hydrogen sulfide are oxidized by this coating and converted to insoluble oxides. As the conversion is completed, these oxides attach to the grains and are removed from the water. Simply stated, the iron ions are being converted from the dissolved ferrous form by oxygen held on the coating of the beads. The oxygen is replaced automatically by regeneration with potassium permanganate. A one to two ounce solution per ft3 of greensand will replenish the depleted oxygen for renewed removal capacity of iron, manganese or sulfur. Inert suspended matter down to 20 micron is also removed by the compactness of the greensand.
