Project 12: University of Luxembourg – Bechmark study

Planning Realisation Monitoring Evaluation
University of Luxembourg – Bechmark study

Energy consumption on wastewater treatment plants (WWTPs) differ due to wastewater characteristics, treatment technology, plant design and effluent standards. There are several options for reducing the amount of energy that is used in the urban water cycle. WWTPs have a central role because a lot of energy is used for the treatment of the wastewater. Additionally, a part of the organic waste is used to produce biogas as renewable energy.

In the countries in North-western Europe different technologies and methods for reducing energy and increasing energy production on WWTPs are being used.  Energy consumption and methods for energy analysis also differ in this region. To get insight in the performance of these different methods and technologies a benchmarking study about the energetic situation of WWTPs in North-western Europe is needed. In INNERS the university of Luxembourg performs this study that focuses on differences in wastewater composition, WWTP design, effluent requirements and used technologies for wastewater treatment.

Results

  1. Comparison of the energy consumption of WWTPs in North-western Europe.
  2. Detailed energy analysis on WWTPs in Luxembourg.
  3. Comparison of several plants in the North-western Europ region.
  4. Inventory report on technologies, processes and methods for reducing energy consumption and optimising energy production.

Planning

April 2011 until the end of 2013.
