Birm is used to remove dissolved iron and manganese. The pH must be above 6.8 and dissolved oxygen content must be equal to 15% of the iron and manganese content. No regeneration is required, only periodic backwashing. The physical characteristics of Birm provide an excellent filter media which is easily cleaned by backwashing to remove the precipitant. Birm is not consumed by iron removal and therefore offers a tremendous economic advantage over many other iron removal methods. Birm filter media is not meant for removal of hydrogen sulfide or that rotten egg smell. Manganese greensand filter is used for removing hydrogen sulfide or rotten egg odor. Some of the advantages of Birm water treatment media include long material life with relatively low attrition loss, a wide temperature performance range, and extremely high removal efficiency. Birm water filtration media may be used in either pressurized or gravity fed water treatment systems. Birm media acts as an insoluble catalyst to boost the reaction between dissolved oxygen (D.O.) and iron compounds. Iron removal efficiency is very high. In ground water, dissolved iron is normally in the ferrous bicarbonate state due to the excess of free carbon dioxide and is not filterable. Birm filter media acts as a catalyst between the oxygen and soluble iron compounds and enhances the oxidation reaction of Fe++ to Fe+++ and produces ferric hydroxide which precipitates and is easily filtered.
  • Birm media is easily cleaned by backwashing to remove the ferric hydroxide. It is not consumed in the iron removal process and therefore provides a positive economic advantage over many other iron removal medias.
  • Birm water treatment media is also used to achieve manganese reduction.
  • When used to reduce manganese, the water to be treated should have a pH between 8.0 and 9.0 for best results.
  • If both manganese and iron are to be removed, the treated water should have a pH below 8.5.
