Abstract:
1. An apparatus comprising: a vessel equipped with a stirring mechanism and a reflux; a dosing unit; a mixer unit operatively connected to the dosing unit; a separation unit operatively connected to the mixer unit; a magnet or an electromagnet for applying magnetic field to the separation unit; a collection unit operatively connected to the separation unit which collects used magnetic reactants; a clean water tank for collecting from the separation unit a substantially clean aqueous fluid, which is substantially free of impurities; a first valve provided in a fluid line between the dosing unit and the mixer unit; a dosing pump to control an amount and kind of magnetic extractants from the dosing unit to be introduced into the mixer unit; a second valve in a fluid line between the collection unit and the separation unit; a third valve in a fluid line between the mixer unit and the separation unit; a fourth valve in a fluid line between the separation unit and the clean water tank which allows the substantially clean aqueous fluid to flow from the separation unit to the clean water tank; a fifth valve in a return fluid line between the separation unit and the clean water tank which allows the substantially clean aqueous fluid to flow from the clean water tank to the separation unit; and a cleaning pump in the return fluid line between the clean water tank and the fifth valve in the return fluid line.
