Thyssenkrupp Steel Europe AG operates the Wehofen-Nord landfill site in the district of Wesel for the disposal of waste mainly from iron and steel production. The resulting leachate is treated in a leachate treatment plant before being discharged into the Emscher River.
Due to the gradually increasing nitrogen parameters in the influent, the degradation of these parameters was to be investigated in pilot tests using an activated carbon fixed bed biology. After successful tests on the resulting leachate, the next step will be to scale up the process to a larger scale and test it using a pilot plant.
