Additions of chemicals to influent or backwash water which contacts Birm media may inhibit iron or manganese removal or may break down or coat Birm media. Chlorination greatly reduces Birm's activity. High concentrations of chlorine compounds may deplete the catalytic coating. Polyphosphates are known to coat Birm and reduce Birm's ability ...

Birm® is an efficient and economical media for the reduction of dissolved iron and manganese compounds from raw water supplies. It may be used in either gravity fed or pressurized water treatment systems. If the removal of Manganese is also required, we recommend the use of Manganese Greensand, as Birm requires a pH of above 8.

Birm acts as an insoluble catalyst to enhance the reaction between dissolved oxygen (D.O.) and the 'iron compounds. ...









In plain English, as water containing iron flows through the media, if there is enough oxygen in the water, the Birm causes the iron to form rust, or solid iron particles. After these rust particles get trapped in the filter media, once or twice a week they are automatically backwashed out to drain, and the filter media is ready to filter again. Q.





Birm filter media will not take out iron when the pH in the well water is under 6.9. While lowest in cost, Birm doesn't last that long and may need to be changed every few years. Greensand Filters. Just like Birm, Greensand has a thin coating of manganese dioxide. However Greensand does remove manganese as well as hydrogen sulfide odors.
