Abstract (en)
[origin: WO2022200683A1] A method for reducing the amount of chlorate in wastewater treated in a wastewater treatment process (1) is disclosed. The wastewater treatment process is operated using a system comprising an equalization basin (5, 6, 7) to which at least a part of the wastewater (8, 9) is fed during the wastewater treatment process, and the method comprises adjusting the conditions in the equalization basin (5, 6) to which the at least the part of the wastewater is fed so as to maintain conditions suitable for the reduction of chlorate in the at least the part of the wastewater, such that the chlorate is at least partially reduced in the equalization basin.
