Birm® |
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 feed or pressurized water treatment systems. Birm acts as an insoluble catalyst to enhance the reaction between dissolved oxygen and the iron compounds. In ground waters, 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 rate 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 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. |
