BirmŪ 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 pressur ized water treatment systems. BirmŪ 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.
BirmŪ, 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 recipitates and may be easily filtered.
The physical characteristics of BirmŪ provide an excellent filter media which is easily cleaned by backwashing to remove the precipitant. BirmŪ is not consumed in the iron removal and therefore offers a tremendous economic advantage over many other iron removal methods.
BirmŪ may also be used for manganese removal with the
same dependability 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.
