Iron and manganese removal
Birm® is a granular filter media for the purification of water from soluble iron and manganese compounds.
The Birm® filter media can be used in both pressure and non-pressure water supply systems.
Birm acts as a catalyst accelerating the oxidation reaction of Fe2+ to Fe3+ with oxygen dissolved in the water. As a result of the following hydrolysis, insoluble residue Fe(OH)3 is formed, which is removed from the water by filtration.
Removal of the residue filtered in the operating mode from the layer of the media is performed during backwash.
