Nachhaltige Sickerwasserbehandlung mit Membran Prozessen

The compliance of the EU regulations including the Landfill and Urban Wastewater Treatment Directives demand for the application of technologies that allow in a cost effective way the sustainable treatment of the leachate generated as a by-product in landfill sites.

Membrane processes (NF, RO) have been successfully applied in the treatment of landfill leachate since thequality of the treated liquid fulfills the discharged limits stipulated by the corresponding environmental authorities. However, the landfill leachate treatment processes are characterized by their high energy demand especially for the treatment of the retentate generated during the membrane stages which results in elevated operational costs.

Even though, the application of the EU Landfill directive has led to the reduction of leachate volumes across the union, still there is a need for finding ways that allow not only the further reduction of the generated concentrate but also the application and implementation of alternative technologies that can lead to a more sustainable membrane treatment process.

Our general objective is thedevelopment of projects related to the application and implementationof alternative technologies that can lead to a more sustainable approach for the treatment of landfill leachate with membrane processes.
