Abstract: A process for the treatment of wastewater (S1) formed during the production of starches, in particular of chemically modified starches, and which contains dissolved salts and organic compounds, in which process it is proposed that the wastewater (S1) or pretreated wastewater (S1) containing substantially the dissolved salts and the organic compounds of the wastewater (S1) is subjected to a membrane separation process in which a separation of the wastewater (S1) supplied to the membrane separation process into a first volume flow (S3) with a higher concentration of dissolved salts in relation to the supplied wastewater (S1) and a second volume flow (S2) with a reduced concentration of dissolved salts in relation to the supplied wastewater (S1) is performed, wherein the first volume flow (S3) is subjected to thermal treatment for the separation of the dissolved salts and of a third volume flow (S9) which contains a fraction of the organic compounds of the wastewater (S1).
