Chemical Requirements for Iron Oxidation
Chemical Requirements for Iron Oxidation
| | Oxidant | Amount needed to oxidize 1 ppm Iron |
|---|
| Oxygen (02) | 0.14 ppm | | Chlorine (C12) | 0.62 ppm | | Ozone (03) | 0.86 ppm | | Potassium Permanganate (Kmn04) | 1.00 ppm | | Iodine (I3) | 3.60 ppm | | Hydrogen Peroxide | 0.50 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 Mn |
|---|
| Oxygen (02) | 0.21 ppm | | Chlorine (C12) | 2.00 ppm | | Ozone (03) | 1.60 ppm | | Potassium Permanganate (Kmn04) | 2.70 ppm | | Iodine (I3) | 7.20 ppm | | Hydrogen Peroxide | 1.00 ppm |
The minimum retention Time for the above is 20 minute with the exception of potassium permanganate
which requires 25 minute and iodine which requires 30 minutes.
| Chemical Requirements for Hydrogen Sulfide Oxidation | | Oxidant | Amount needed to oxidine 1 ppm H2S |
|---|
| Chlorine (c12) | 3.00 ppm | | Potassium Permanganate (KMn04) | 6.00 ppm | | Iodine (I3) | 10.8 ppm | | Hydrogen Peroxide (H202) | 1.05 ppm | | Ozone (03) | 2.00 ppm |
The minimum contact time for the above oxidizing
agents is 30 minutes with the exception of potassium permanganate
which requires 35 minutes and iodine which is 45 minutes.
