Technical, Economic, and Environmental Assessment of Wastewater and Sludge Management Solutions Designed to Overcome Common Issues

Artikel i vetenskaplig tidskrift, 2014

In order to support decision-making in design of wastewater and sludge management within the European Union, the EU FP7 project ROUTES has performed technical development aimed at sludge minimisation, the enabling of agricultural use of sludge and sludge resource recovery. Technical, economic and environmental assessment has been performed for ten case studies in which model (non-existent) reference plants of different size and configuration, representative of real wastewater treatment plants in Europe, have been considered to be upgraded to solve different common problems, based on the new knowledge from the technology development carried out within the project. This paper reports on the methodology used in the assessment with examples of obtained results for three of the case studies. The methodology in particular highlights some critical points that need further attention when similar upgrading is considered in real cases.
