Abstract (en)
[origin: WO2013023911A1] The invention relates to a method for reprocessing waster water (2) from an industrial process, comprising an organic acid. Said method comprises the following steps: the waste water is introduced into a heat exchange process in which a heat exchange medium (4) is used so that the waste water (2) which is to be treated is heated to a temperature between 60 ° C and the boiling point of the waste water (2). Subsequently, the waste water is partially evaporated and re-condensed, said waste water (2) being radiated with UV radiation (6) during the evaporation and condensation process in the liquid and/or gas phase. As a result, a chemical transformation of the organic acid in H2O and carbon dioxide is at least partially carried out. Then, the condensed part of the purified waste water (24) is fed back into the industrial process.
