In the Venice Living Lab the application of resource recovery and circular economy in the field of water, especially wastewater, are strategic to achieve climate change resilience. Currently, the pursuit of these goals is slowed and prevented due to several issues (technical but mainly regulatory) related to wastewater process management, not much to effluents from wastewater treatment plants, rather when referring to nutrients and sludge. The limits and slowdown of the virtuous paths towards resource recovery and circular economy are also sensibly linked to a lack of shared and transparent knowledge on the quality and opportunities connected to the reuse itself, and to an overevaluation of risks which together lead to a low social acceptance. There are several goals in Venice LL: i) the contribution to complete the reuse goals envisaged (but not still reached) by another important funded regional project (the Integrated Fusina Project PIF) which, alongside other important reclamation goals for the industrial area, provides for the reuse of the effluent of the municipal treatment plant (WWTP) Fusina for "non-potable" purposes; ii) the possibility of resource recovery from wastewater processes for high quality fertilizer production and carbon footprint reduction; iii) tackling the tough issue of the management of sludge produced by municipal WWTPs, still profoundly conditioned by a limited vision and knowledge which condition the choice and can hinder the pursuit of the most sustainable management pathway (such as its physiological destination to the environment and to the soil).
The main technical solutions prosed are: i) a combinatory pilot plant (UF unit + RO unit + EDI unit), tested on Fusina WWTP effluent for industrial water reuse; ii) two pilot stripping technologies, tested on concentrated WWTP stream(s) for ammonium sulphate production; iii) two IT platforms, the Water Reuse Strategic Platform and the Sludge Management Platform, to assess the best reuse opportunities and valorization pathways firstly at local/Regional scale and then trasferable at National/EU scale for water and sludge respectively.
