Aqmos Birm - filter granulate for the removal of iron and manganese

BIRM® is a specially developed black filter granulate which is coated with manganese dioxide (MnO2) and oxidizes iron and manganese using catalysis and then filters them off. The BIRM® filter material is not exhausted if oxygen is dissolved in the water. The manufacturer states that a content of 15% of the dissolved iron is sufficient (1 mg / l Fe therefore requires 0.15 mg / l O2). This means that BIRM® does not have to be regenerated, just rinsed. BIRM® can also be used to remove manganese at stable pH values ??in the raw water of 8.0 to 8.4. However, the removal of iron at this pH is no longer optimal. BIRM® must not come into contact with strong oxidizing agents such as chlorine or potassium permanganate.
