Based on the results from the environmental LCA, the economic LCC, the enabling and constraining factors for a successful technology implementation and Unique Selling Propositions, recommendations for the actual implementation of the technologies studied in WA1-4 were developed. This goal builds upon a synthesis of the efforts from the other work packages in WA5 and is tightly linked to the WA1-4 of the DEMEAU project through case studies. Therefore, clear responsibilities within WA5 for the coordination with other work areas had been established from the onset of the DEMEAU project.
Nine micropollutant substances have been identified as high priority substances to be reported in all case studies based on their environmental relevance, coverage of chemical and physical properties, elimination rates by various technologies and existence of an analytical method to identify them. Characterization factors for the toxicity model USEtox® have been developed for all these substances based on the EPISuite v4.1 software for physico-chemical properties, data from project partners (EAWAG) for aquatic toxicity properties and a literature review for human toxic properties.
LCA was conducted for five different case studies in detail: Managed Aquifer Recharge (MAR) system near Barcelona (Sant Vicenc dels Horts, ES) for groundwater recharge, MAR system at Dunea (NL) for drinking water production, Automatic Neural Net Control System (ANCS) for membrane plant for backwash water treatment at WAG (GER), powdered activated carbon adsorption with subsequent ultrafiltration (PAC+UF) pilot plant in Basel (CH), and ozonation of WWTP effluent at Neugut (CH).
This deliverable presents a multi-stakeholder assessment of implementation drivers and barriers throughout various subsequent stages of the innovation cycle. Enabling factors (drivers) and constraining factors (barriers) for the implementation of the four innovative DEMEAU technologies that form the core of Work Areas 1 to 4 are identified at four different analytical levels (contextual, inter-organizational, intra-organizational and individual level) from the perspectives of various stakeholders that are involved in six selected case studies.
