AIO for Iron and Sulfur – Chemical-Free Well Water That Actually Works

Description

Air Injection Oxidation (AIO) has become the standard for well water owners battling iron and sulfur—contaminants that stain fixtures orange and make water smell like rotten eggs. Unlike chemical feed systems requiring potassium permanganate or chlorine, AIO uses only air to oxidize dissolved iron and hydrogen sulfide, then filters out the resulting particles in a single tank.

The control valve creates a compressed air pocket (15–35% of tank volume) during each backwash cycle. As water flows through this zone, oxygen converts ferrous iron and H₂S into filterable solids trapped by catalytic carbon or Katalox Light media. Real-world systems handle 3–12 ppm iron and 2–8 ppm hydrogen sulfide—covering most residential wells. Premium setups with Katalox Light push those limits to 20–30 ppm iron.

AIO struggles with iron bacteria, pH below 6.5, or cold water under 50°F, but for moderate iron levels and decent well flow, it delivers chemical-free removal with minimal maintenance. Set the backwash frequency based on your iron load and household size, then let it run.
