BirmMedia is a black catalytic media used for removing soluble iron, manganese, hydrogen sulfide, arsenic and radium from water supplies. The media has unique characteristics in addition to its catalytic property which facilitates the oxidation reduction reaction of iron and manganese.  Birm Media can be used at high operating temperatures and high differential pressures without breakdown of the media and is classified as a “high rate” media where the filters can be run at very high linear velocities with excellent results. Unlike other medias, it does not require extensive pre-conditioning. Birm Media effectively removes iron, manganese and hydrogen sulfide from natural waters. Water for industrial and domestic uses must be substantially iron and manganese free. In many countries it is a requirement that water for municipal use should not contain iron and manganese concentrations of greater than 0.2 and 0.05 ppm respectively, and preferably below0.05 and 0.02 ppm. In certain industries like pulp and paper mills, tanneries, textile plants, dye houses and laundries, it is almost impossible to operate with iron or manganese bearing waters since they would produce objectionable stains, streaks, spots and off-colors on many manufactured products. Iron and manganese also foul ion exchange resins. Hence, it is necessary to include a pretreatment stage in most ion exchange processes
