The Niagara+™ Birm Iron Filter efficiently removes iron where hydrogen sulfide (rotten egg odor) is NOT present, organic matters do not exceed 4 ppm and pH level is greater than 6.8 The Birm Iron filter will also remove Manganese in applications where the Ph level is between 8 and 9.
More Information about Iron Removal
Birm Iron Filter
Our Birm Iron Filters can remove up to 10 ppm of both ferric (oxidized) and ferrous (clear) iron and 5 ppm of manganese. Birm is an aluminum silicate media coated with manganese dioxide. This coating is highly concentrated with oxygen and acts as an insoluble catalyst to enhance the reaction between dissolved oxygen and the the iron compounds. In essence, the dissolved iron is oxidized at the surface of the media into a rust particle that can be effectively filtered from the water. The precipitated iron and manganese can then be easily removed from the system during backwash. No chemical regeneration is required and nothing is imparted into the drinking water.
For Birm to effectively remove iron, the pH of the raw water must be greater than 6.8. If both Iron and Manganese are present, the pH should be between 7.5 and 8.5. For Manganese removal the pH should be between 8.0 and 9.0 for best results.
The water must have a dissolved oxygen content equal to at least 15% of the iron content. Since many waters do not have a high content of dissolved oxygen, an air injection system is recommended in conjunction with the Birm Filter for most effective operation.
Operated under proper conditions, the Birm Iron Backwash filter requires no chemical for maintenance and regeneration is not required. Iron removal efficiency is extremely high, with only periodic backwashing required. The Birm Filter Media is a durable material with a long life and a wide temperature range.
Our automatic backwash systems are equipped with the FleckŪ 5600 water conditioning control valve.
