Dose Breakdown
| Contaminant | Level | H₂O₂ Needed |
|---|
Manganese: Peroxide is not recommended for manganese. For manganese, ask us about chlorine injection with a Pro-OX or GreensandPlus filter: 888-600-5426.
Important: These ratios give initial doses. Actual demand may vary based on water chemistry. After installation, test for peroxide residual downstream — a slight residual (0.2–1.0 ppm) after the contact tank confirms adequate dosing. If you see no residual, increase the dose. Excess H₂O₂ is removed by the catalytic carbon filter downstream.
Standard H₂O₂ Dosing Ratios
| Contaminant | H₂O₂ per 1 ppm | Notes |
|---|
| Iron (Fe) | 1.0 ppm | 1:1 ratio, oxidizes ferrous → ferric |
| Manganese (Mn) | Not recommended | See manganese note below |
| Hydrogen Sulfide (H₂S) | 2.0 ppm | 2:1 initial dose |
Manganese: Peroxide is not recommended for manganese. For manganese, ask us about chlorine injection with a Pro-OX or GreensandPlus filter: 888-600-5426.
