One Cubic Foot Green Sand Filter




Manganese green sand filters pull iron and sulfur from water.
Green sand media requires a chemical called potassium permanganate.
Permanganate coates over the green sand every time it backwashes.
Permanganate is a strong oxidizer to iron and sulfur. As the water runs thru the green sand the permanganate oxidized the iron and sulfur so the green sand can remove it.
