Birm - Iron & Managanese Removal 1 Cubic Foot

 Birm® is an efficient and economical method of removing dissolved iron and manganese compounds from raw water supplies.   Birm®  acts as an insoluble catalyst to enhance the reaction between dissolved oxygen (D.O.) and the iron compounds.   In ground water the dissolved iron is usually in the ferrous bicarbonate state due to the 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 + + to Fe + + + and produces ferric hydroxide which precipitates and may be easily filtered.   The physical characteristics of Birm® provide an excellent filter media that 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.   Other advantages of Birm®: Long material life with relatively low attrition loss, Wide temperature performance range
