  • Birm ( 45.25 lbs) 1 Cu. Ft. Box: Birm is an efficient and economical method of removing dissolved iron and manganese compounds from raw water sup-plies.
  • It may be used in either gravity fed or pressur izedwater treatment systems.
  • Birm 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.
  • Birm, acting as a catalyst between the oxygen and the soluble ironcom pounds, enhances the oxidation reaction 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 and therefore offers a tremendous economic advantage over many other iron removal methods.
  • Birm may also be used for manganese removal with the same dependability as iron removal but the water must be treated to 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 ironremoval.
  • BirmAdvantages: Under the proper conditions, no chemicals to purchase for maintenance.
  • Regeneration not required.
  • Iron removal efficiency is extremely high.
  • Durable material with a long life and wide temperature range.
  • Weighs only 46-50 lb./cubic foot.Physical Properties: Color - Black Density - 47-50 lbs./cu. ft.
  • Effective Size - 0.61 mm Uniformity Coefficient - 1.72
