Iron/Sulfur Systems

Greensand

  • Manganese Greensand forms from glauconite green sand.
  •  When water chemistry is within certain parameters it is capable of reducing iron, manganese and hydrogen sulfide from water through the process of oxidation and filtration.
  • Soluble iron and manganese oxidizes and precipitates through contact with higher oxides of manganese on the greensand RP7 iron/sulfur systemgranules.
  • The hydrogen sulfide is reduced by oxidation to an insoluble sulfur precipitate.
  • Backwashing filters and removes precipitates. When the oxidizing capacity power of the Manganese Greensand bed exhausts, the bed has to be regenerated with a weak potassium permanganate solution, thus restoring the oxidizing capacity of the bed.
  •  One to two ounces of potassium permanganate, in solution, per cubic foot of Manganese Greensand is considered sufficient for normal regeneration.

         Don’t Forget!

  • Vigorous backwash and regenerating the bed is required when placed in service, and before its oxidation capacity is totally exhausted.
  • Operating the bed after oxidation capacity is exhausted will reduce its service life and may cause staining.

 

RP8 iron/sulfur systemOdor Oxidizer

  • An odor oxidizer removes sulfur odor by converting Hydrogen Sulfide into water and precipitated sulfur compounds.
  • The unit uses a booster pump and contact tank, sometimes two of each, if sulfur levels are very high, or if high flow rates are expected.
  • The unit is very reliable, requires no regeneration, and no chemicals to purchase.
  • Twice a year simply open a drain valve to flush out any sediment. An added bonus is the extra water pressure to the house from the booster pump!!
  • Basically, once installed you can forget about it!
