This system uses Air Injection Oxidation (AIO) to oxidize dissolved iron and manganese, allowing them to be captured and filtered by Birm media. No chemicals, no permanganate, and no chlorine injection required.
It is best suited for:
Iron: up to ~1.0 mg/L
Manganese: up to ~0.05 mg/L
pH: 7.0 or higher
No hydrogen sulfide (rotten egg smell)
Birm is a catalytic filtration media that accelerates oxidation without being consumed or regenerated. Because oxidation is supplied by the AIO head, Birm offers:
Long media life
No chemical handling
Low pressure drop
Simple backwashing maintenance
⚠️ Birm requires dissolved oxygen and proper pH, which is why it is paired with an AIO control valve.
Before selecting this system, a few things should be considered:
pH must be 7.0+
Iron and manganese should be low to moderate
Not recommended for sulfur or high iron wells
Birm requires sufficient contact time and proper flow. Oversizing is preferred.
Approximate recommended service flow rates:
1.0 cu ft: up to ~5–6 GPM
1.5 cu ft: up to ~7–9 GPM
2.0 cu ft: up to ~10–12 GPM
If you’re unsure of your flow rate, a simple bucket test from a hose bib, bathtub, or tank tee works very well. Well pump output is often the limiting factor.
