Abstract: Treatment of wastewater from an aldolization process, containing dissolved and/or dispersed organic impurities, comprises acidifying the wastewater to pH 0-6 and extracting it with an organic liquid produced by stripping the acidified or acidified and extracted wastewater, condensing the stripped compounds and phase-separating the condensate. An independent claim is also included for treatment of wastewater from an aldolization process, containing dissolved and/or dispersed organic impurities, by acidifying the wastewater to pH 0-6, extracting it with an organic liquid and removing volatile organic impurities and a stripping apparatus, where the organic liquid is a low boiler fraction from the distillation of a crude alcohol produced by hydrogenating an aldehyde, the alcohol/aldehyde being n-butanol/n-butyraldehyde, isobutanol/isobutyraldehyde, n-pentanol/n-valeraldehyde, n- and isopentanol/n- and isovaleraldehyde, 2-ethylhexanol/2-ethylhexenal and/or 2-propylheptanol/2-propylheptenal.
