METHOD FOR RECOVERING PHOSPHATE SALTS FROM A LIQUID

摘要

The invention relates to a method for completely separating phosphate from a liquid and for recovering phosphate salts in a reactor, which is equipped with two groups of electrodes having differing polarities, wherein the sacrificial electrodes consist of a magnesium-containing material, and wherein said method comprises the following method steps: the application of a voltage to the electrodes; the continuous flow of the liquid through the reactor; the precipitation of phosphate salts from the liquid; and the settling of the crystals in the cone-shaped bottom of the reactor. For a galvanic procedure, no voltage is applied to the electrodes.
