TREATMENT OF ACIDIC WATER CONTAINING DISSOLVED FERROUS CATIONS |
摘要 |
<p>A water treatment process for raw water containing dissolved Fe2+ and H+ cations to reduce the Fe2+ cation concentration therein involves oxidation of the Fe2cations to Fe3+ cations with the formation in the water of solid Fe(OH)3 from the Fe3+ cations. The process comprises the steps of oxygenating the water and raising the pH of the water. The oxidation of the Fe2+ cations and the fromation of the Fe(OH)3 are carried out in the presence of suspended particulate material in the water, the particulate material being present in the water at a concentration of at least 5 g/l.</p> |
