A8006 Birm Iron, Manganese and Hydrogen Sulfide Filter Media (1 Cu Ft 38 lb)

PRODUCT DOCUMENTATION

• A8006 Birm Iron and Manganese Removal Filter Media

Birm® is an efficient and economical media for the reduction of dissolved iron and manganese compounds from raw water supplies. It may be used in either gravity fed or pressurized water treatment systems. Birm acts as an insoluble catalyst to enhance the reaction between dissolved oxygen (D.O.) and the iron compounds. I
