Birm is a black granular filter material used for removal of iron and/or manganese from water in pressure or gravity systems. It contains an active insoluble catalyst to precipitate iron and/or manganese. Because the presence of iron is most common, iron removal is the usual application for Birm. Under suitable conditions, the iron and dissolved oxygen in water react on contact with the Birm filter bed and, as a result, the iron is precipitated in the form of hydroxide. This is a flocculent material which is filtered out in the bed of Birm. Periodic backwashing flushes out the accumulated iron and the Birm is again ready to perform its function. Birm is not consumed in the iron removal operation.

Conditions necessary for the use of Birm

Iron Removal

No hydrogen sulphide present.

Organic matter not to exceed 4-5 ppm as indicated by the oxygen consumed value.

Oil must not be present.

A dissolved oxygen content of at least 15% of the iron. (Example Iron = 10ppm.
Dissolved Oxygen = 1.5 ppm or more).

A pH of 6.5 or higher.

Manganese Removal

·         The removal of manganese from water by the catalytic action of Birm usually s a higher pH than is d for iron removal. Such water should have a pH in the range of 8.0-9.0.

·         The dissolved oxygen content should be 15% or more of the total manganese and iron expressed in ppm.

·         Other conditions are the same as for iron removal.
For manganese removal, consult our laboratory.

·         General data

·         Birm is furnished in two grades: regular and fine. Regular Birm is generally recommended for industrial and municipal installations. Fine Birm is recommended for domestic application or in cases the available backwash water is limited. Bed expansion of 35 to 50% in backwash is d for best results. 12 to 15 GPM per square foot are d for backwashing regular Birm. 8 to 10 CPM per square foot are d for fine Birm.
