Visit the Material Specification Product Information page to learn more about our Birm filter media.
Birm Media - Birm is a granular filter media manufactured by the Clack Corporation. It''s a chemical free way to reduce iron and manganese in your water supply. Birm acts as a catalyst to enhance the reaction between dissolved oxygen and the iron in your water – oxidizing the iron to a insoluble (ferric) compound – removing the accumulated iron from the filter bed during the automatic backwashing process. 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 include; long material life with relatively low attrition loss, a wide temperature performance range, and extremely high removal efficiency. When using Birm for iron removal, it is necessary that the water contain no oil or hydrogen sulfide, organic matter not to exceed 4-5 ppm, and the dissolved oxygen content must be equal to at least 15% of the iron content with a pH of 6.8 or more. Chlorination greatly reduces Birm’s activity, as high concentrations of chlorine compounds may deplete the catalytic coating.
