| Chemical Requirements for Iron Oxidation | |
|---|---|
| Oxidant | Amount Needed to Oxidize 1 ppm Iron |
| Oxygen (O2) | 0.14 ppm |
| Chlorine (Cl2) | 0.62 ppm |
| Ozone (O3) | 0.86 ppm |
| Potassium Permanganate (KMnO4) | 1.0 ppm |
| Iodine (I3) | 3.6 ppm |
| Hydrogen Peroxide (H2O2) | 0.5 ppm |
The minimum retention time for the above is 20 minutes, with the exception of iodine which needs 25 minutes.
| Chemical Requirements for Manganese Oxidation | |
|---|---|
| Oxidant | Amount Needed to Oxidize 1 ppm Iron |
| Oxygen (O2) | 0.21 ppm |
| Chlorine (Cl2) | 2.00 ppm |
| Ozone (O3) | 1.60 ppm |
| Potassium Permanganate (KMnO4) | 2.70 ppm |
| Iodine (I3) | 7.20 ppm |
| Hydrogen Peroxide (H2O2) | 1.00 ppm |
The minimum retention time for the above is 20 minutes, with the exception of potassium permanganate which requires 25 minutes and iodine which needs 30 minutes.
| Chemical Requirements for Hydrogen Sulfide Oxidation | |
|---|---|
| Oxidant | Amount Needed to Oxidize 1 ppm Iron |
| Chlorine (Cl2) | 3.0 ppm |
| Ozone (O3) | 2.0 ppm |
| Potassium Permanganate (KMnO4) | 6.0 ppm |
| Iodine (I3) | 10.8 ppm |
| Hydrogen Peroxide (H2O2) | 1.05 ppm |
The minimum retention time for the above is 30 minutes, with the exception of potassium permanganate which requires 35 minutes and iodine which needs 45 minutes.
