Abstract

In this study organic solutes in final clarifier effluents of a rural and an urban wastewater treatment plant discharged to German rivers were analyzed: COD, DOC, free fatty acids, triacyl glycerols, carbohydrates, proteins, humic acids, anionic and nonionic detergents, hydrocarbons, AOX as well as gas chromato- graphically detectable substances. To the rural sewer no significant industrial effluents were discharged while about 30 % of the wastewater treated in the urban plant were estimated to be of industrial origin. In the investigated effluents 30 to 40 % of DOC could be related to classes of organic compounds measured as sum parameters. In the urban effluent DOC and COD were lower, but concentrations of gas
