Birm Media – Iron Removal Media

Pure water has no taste, but water is a natural solvent. Most minerals from groundwater, including iron are dissolved by water. Large amounts of iron in drinking water can give it an unpleasant metallic taste.

Iron in Drinking Water

The most noticeable effect of water that is high in iron is that the water tastes metallic. The water may be discolored and appear brownish, and it may even contain sediment. Iron will leave red or orange rust stains in the sink, toilet and bathtub or shower. It can build up in your dishwasher and discolor ceramic dishes. It can also enter into the water heater and can get into the laundry equipment and cause stains on clothing. The health bodies caution that although iron in drinking water is safe to ingest, the iron sediments may contain trace impurities or harbor bacteria that can be harmful. Iron bacteria are naturally occurring organisms that can dissolve iron and some other minerals. These bacteria also form a brown slime that can build up in water pipes. Iron bacteria are most commonly problematic in wells, where water has not been chlorinated.

Role of Birm Media in iron removal from water

Birm Media is an efficient and economical media for the reduction of dissolved iron and manganese compounds from raw supplies. Birm Media acts as an insoluble catalysts to enhance the reaction between dissolved oxygen (D.O.) and the iron compounds

In ground waters the dissolved iron is usually in the ferrous bicarbonate state due to excess of free carbon dioxide and is not filterable. Birm, acting as a catalyst between the oxygen and the soluble iron compounds, enhances the oxidation reaction of Fe(2) to Fe(3) and produces ferric hydroxide which precipitates and may be easily filtered.

The physical characteristics of Birm Media 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.

Features :
* Regeneration not required
* High Iron removal efficiency
* Negligible labor cost. Only periodic backwash is required
* Durable Material. Long life.
* Wide temperature range
* Weighs only about 17 kgs/cu ft.
