Chlorine Dioxide (ClO₂): Why This “Smart Oxidizer” Hits Microbes Where It Hurts
Think of most disinfectants as big hammers. ClO₂ is more like a targeted multitool: it reacts decisively with a few critical “weak links” in microbes, works across a broad pH range, penetrates biofilms, and avoids chlorinating organic matter (so it doesn’t make THMs/HAAs). Its main byproduct is chlorite, which is tightly regulated in drinking water.
