Manganese Greensand Filters with Automatic Backwash for Iron Reduction

Manganese Greensand is capable of reducing iron, manganese and hydrogen sulfide from water through oxidation and filtration.

Manganese Greensand is formulated from a glauconite greensand which is capable of reducing iron, manganese and hydrogen sulfide from water through oxidation and filtration. When the oxidizing capacity power of the Manganese Greensand bed is exhausted, the bed has to be regenerated with a weak potassium permanganate (KMnO4) solution.

Ordering Notes:

  • Manganese greensand filters up to 14″ can be regenerated intermittently with potassium permanganate regeneration tank, or continuously with an oxidant injection system (both sold separately). Filters with tank diameter of 16″ and larger require continuous injection of potassium permanganate or oxidizing chemistry which will require a tank and feeder. The size of the injection system (sold separately) and dosage rates will be dependent on the water quality. Please consult an AMI representative for guidance.
  • Greensand Filters are available with USA or European style plugs and voltages. Please add the appropriate voltage code to the end of the model when ordering.
    • 120V AC/60Hz with USA cord = US
    • Example: W-MFI744GET-US
    • European 220V AC = EU (EU plug is removable to convert into universal 220v cord)
  • 5 gpm per sq. ft. of media is the best design condition for filtration. For relatively clean water, you may go up to design criteria of 15 gpm per sq. ft. Backwash flow rate based on 25 psi pressure drop.
  • Skid mounting, control panel and custom sizes and configurations are available upon request. AMI Auto Backwash Iron Filters are offered standard with new state of the art electronic programmable valves, but may be ordered with electromechanical Fleck valve heads upon request.
