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.

Where sand, grit, iron, manganese, and other suspended matters are the problem. Krudico Sand Filters offer a more economical method of removal than other media. The media, alumina silicate, (also known as Filter Lite or Filter Ag) has an irregular but larger shape than other aggregate media. The irregular form makes the bed ideal for trapping particulate matter while the larger sized particles allow for higher flow rates than other media.

The SFA Filter has been the most popular filter for removing Iron & Manganese when used in conjunction with Krudico’s "Air Charger" aeration systems.
