Birm®(P/N LC10001)is an efficient and economical media for the reduction of dissolved iron and manganese compounds from raw water supplies. Birm® is not consumed in the iron removal operation and therefore offers a tremendous economic advantage over many other iron removal methods. Birm® is an efficient and economical media for the reduction of dissolved iron and manganese compounds from raw water supplies. Birm is an efficient and economical method of removing dissolved iron and manganese compounds from raw water supplies. When used to reduce manganese, the water to be treated should have a pH between 8.0-9.0 for best results. High pH conditions may cause the formulation of colloidal iron which is very difficult to filter out. Our Birm may also be used for manganese reduction with the same dependability as iron removal. MTM ® (P/N MTM) is a granular manganese dioxide filtering media used for reducing iron, manganese, and hydrogen sulfide from water. They are similar to Birm and Filox but more robust than Birm and cheaper than Filox. In these applications the water to be treated should have a pH of 8.0-9.0 for best results.

When used to reduce manganese, the water to be treated should have a pH between 8.0-9.0 for best results. Birm®, 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 precipitates and may be easily filtered. Oxidizing iron filters use either oxygen injection (with air or pure oxygen), potassium permanganate, chlorine or ozone to aid the filter media in oxidizing the iron. All other conditions remain the same for either manganese or iron removal. Manganese dioxide is used to remove iron and manganese from drinking water by a process of catalytic oxidation. stream Before adding any chemical to the influent or backwash water, the chemical's compatibility with Birm should be thoroughly tested.

Dissolved Oxygen (D.O.) BirmMedia is a black catalytic media used for removing soluble iron, manganese, hydrogen sulfide, arsenic and radium from water supplies. Watts, who sells a manganese dioxide based media under the name of Filox, says that their manganese dioxide media works from a pH of 5 to a pH of 9. CHEMICAL PROPERTIES : Natural manganese ores specially selected for their high catalytic activity, free from contamination and with no additives, are used in the production of this manganese dioxide. and … Pyrolox® functions as a catalyst, but itself remains relatively unchanged. 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, the D.O. Negligible labor cost: only periodic backwashing required. �0�(j(j(0��C Birm cannot be used in presence of any oxidants as this can hamper its performance, which is not the case with Greensand or Filox (but in limited quantity).

A naturally mined ore, Pyrolox® is a mineral form of manganese dioxide which has been used in water treatment for more than 75 years. and the iron compounds. Durable material with a long life and wide temperature range. They require a pH of 7+ for iron removal Birm acts as an insoluble catalyst to enhance the reaction between dissolved oxygen (D.O.) The high manganese dioxide content produces a much more active and energetic medium — … endstream It may be used in either gravity fed or pressurized water treatment systems. High concentrations of chlorine compounds may deplete the catalytic coating. If the influent water has a pH of less that 6.8, neutralizing additives such as Corosex®, Calcite or soda ash may be used prior to the Birm® filter to raise the pH. Just some of the advantages of Birm Media include: -long material life with relatively low attrition loss -a wide temperature performance range and extremely high removal efficiency.
