Method for treating water containing sulfate |
| abstract |
An apparatus and method for removing contaminating metal ions and sulfate ions from acidic aqueous solution such as waste mine water which features passing the solution between pairs of electrodes, each pair of electrodes impressed with a voltage selected according to specific ion species and then adding chemical agents to raise the pH and form precipitates of the metal and sulfate ions. A magnetic field is applied during at least the first mixing step. The precipitate is then separated from the water with settling and filtering steps. The clarified solution is treated by reverse osmosis to concentrate the ammonium. |
