Birm is an efficient and economical method of removing dissolved iron and manganese compounds from raw water supplies. It may be used in either gravity fed or pressurized water treatment systems. Birm acts as an insoluble catalyst 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 an excess of free carbon dioxide and is not filterable. Birm, acting as a catalyst between the oxygen and the soluble iron compounds, enhance the oxidation reaction of Fe__ to Fe___ and produces ferric hydroxide which precipitates of Birm provide an excellent filter media which is easily cleaned by backwashing to remove the precipitant. Birm is not consumed in the iron removal and therefore offers a tremendous economic advantage over many other iron removal methods.

Birm may also be used for manganese removal with the same dependability to as iron removal. In these applications the water to be treated should have a pH of 8.0 to 9.0 for the best results. If the water also contains iron, the pH should be below 8.5 High ph conditions may cause the formation of colloidal iron which is very difficult to filter out. All other conditions remain the same for either manganese or iron removal.
