1 cu/ft Manganese Greensand Filter w/Clack Timer Control Valve

Manganese Greensand is formulated from a glauconite greensand which is capable of removing iron, manganese and hydrogen sulfide from water through oxidation and filtration.

Manganese and soluble iron are oxidized and precipitated by contact with higher oxides of manganese on the greensand granules. The hydrogen sulfide is eliminated by oxidation to sulfate and an insoluble precipitate.

When the manganese greensand bed is saturated, it is regenerated with a weak potassium permanganate solution which is rinsed down the drain. The potassium permanganate is available locally at nearly all hardware and home improvement stores.


  • Manganese green sand filters pull iron and sulfur from water.
  • Green sand media requires a chemical called potassium permanganate.
  • Permanganate coats 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.
  • Use when hardness is low, PH must be 7.2 or above.


  • Iron reduction over wide pH range
  • Effective reduction of hydrogen sulfide in addition to iron and/or manganese
  • No harmful effects from a chlorine feed
  • Low attrition for long bed life
