How the AIO Birm system works

Incoming water passes through a compressed pocket of air contained in the top of the tank. The oxygen in the air precipitates the iron and manganese into solid form and is removed when it passes through the filters birm media bed. Birm acts as a catalyst in the reaction between iron, manganese and oxygen that also causes the iron and manganese to precipitate into a solid. As more water passes through the unit the air becomes depleted and the birm becomes overloaded with the iron and manganese. Periodic automatic regeneration usually every 2 or 3 days replenishes the supply of air and cleans the media of filtered iron and manganese. Birm is not consumed in the removal process and therefore is much more economical than many other iron and manganese removal processes.



  • Superior filtration for iron and  manganese
  • Uses air to precipitate iron, manganese and minor hydrogen sulfide (rotten egg smell)
  • Fully adjustable control valve delivers upflow backwash, air recharge, rapid rinse then downflow service
