Manganese Greensand Filter System: 

Our Iron Filter systems use a high quality manganese Greensand media that effectively remove iron, manganese and hydrogen sulfide (rotten egg odor) usually found in well water. The system is installed in the main water line. When the raw water enters your iron filter it passes down through the filter media and get oxygenated. The oxygen causes precipitation of the minerals and any iron, manganese or hydrogen sulfide present in your water supply is trapped resulting in a clean, filtered water flow to your household. The filter media is periodically regenerated automatically, back washing the trapped minerals to the drain and regenerated by replacing the oxygen. This is done by introducing potassium permanganate to the media. The system comes with the Potassium Permanganate container. With proper installation it removes the following contaminants resulting in a healthier water. 

• 25 ppm of both ferric (oxidized) and ferrous (clear) iron
• 8 ppm of Hydrogen sulfide (rotten egg odor)
• 10 ppm of manganese

Note: These systems are design for water supplies with pH between 5.9 and 8.8. If your water supplies have a pH of 5.8 or less, you need to neutralize pH before passing through this system.
