Abstract (en)
[origin: WO2013023912A1] The invention relates to a method for reprocessing waste water (2) from an industrial process, comprising an organic acid. A base is added to the acid-containing waste water (2) wherein a salt dissolving in the waste water (2') is produced due to a neutralization reaction. Said waste water (2') is subsequently is guided in a heat exchanger process, a heat exchange medium (4) being used such that the waste water (2) which is to be treated is partially evaporated and is condensed into purified water (44) on a condensation device (14). A concentrate enriched with the salt forms a residue and the purified water (44) is guided back into the industrial process.
