Iron Filters – Remove Sulphur, Iron and Manganese

Three Methods for Removing Iron, Sulphur or Manganese from Your Drinking Water

Birm is an efficient and economical method of removing dissolved iron and manganese compounds from raw water supplies. The physical characteristics of Birm provide an excellent filter media which is easily cleaned by backwashing to remove the precipitant. Birm is not consumed by iron removal and therefore offers a tremendous economic advantage over many other iron removal methods. Birm is not meant for removal of hydrogen sulfide or that “rotten egg” odor. A manganese greensand filter, or The Terminator air injection system is more suited for that task.

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 sulfied 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.

Terminator Water Treatment Systems Eliminate iron, sulphur and turbidity without the use of expensive chemicals. The Terminator can correct rusty water stains and rotten egg odors through its filtration system. Periodic backwashing is all that is required to keep The Terminator working at peak performance. Terminator systems are not recommended for water systems using a jet pump.
