Iron Removal Filters

Iron Removal Filters

When it comes to iron removal filtration for applications over 40 GPM, Bikon Water has a media solution to meet your needs.


Birm is a granular filter media commonly used for the removal of iron and/or manganese from well water supplies.

Birm is an efficient and economical method of removing dissolved iron and manganese compounds from raw water supplies. It can be used in either gravity fed or pressurized water treatment systems. Birm acts as an insoluble catalyst to enhance the reaction between dissolved oxygen (DO) and iron compounds. The physical characteristics of Birm provide an excellent filter media which is easily cleaned by backwashing to remove the precipitant. Birm is not consumed in the iron removal operation and therefore offers a tremendous economic advantage over many other iron removal methods. Also, no chemicals are required for regeneration.

Manganese Greensand
Manganese greensand is another filtration media offered by Severn Trent Services. Manganese greensand removes iron, manganese and hydrogen sulfide from water through oxidation and filtration.

Soluble iron and manganese 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. Precipitates are then filtered and removed by backwashing. When the oxidizing capacity power of the manganese greensand bed is exhausted, the bed is regenerated with a weak potassium permanganate solution to restore the oxidizing capacity of the bed.
