Description du projet
Contrôle et amélioration de la qualité de l’eau grâce à une approche intégrée
Outre le fait d’entraîner une pénurie d’eau, la contamination des ressources affecte également la production alimentaire. L’aquaculture représente l’étude de cas idéale pour la gestion des eaux contaminées, car il s’agit de l’industrie alimentaire qui, à l’heure actuelle, connaît l’essor le plus rapide à l’échelle mondiale. Le projet SusWater, financé par l’UE, vise à développer de nouveaux outils durables sur le plan écologique qui éliminent les polluants et traite les eaux contaminées en vue de les réutiliser ou de les destiner à l’aquaculture. SusWater, qui met en œuvre une panoplie de nouvelles méthodes durables en combinant des processus d’adsorption, biotiques et abiotiques pour l’élimination des contaminants qui suscitent de nouvelles préoccupations et la capture d’éléments potentiellement toxiques, présentera un processus de contrôle qui garantit une eau bon marché et sûre du point de vue microbiologique.
Objectif
Nowadays, the contamination of water resources coupled with the increased food demand is becoming a key issue. Concerning water, monitoring the quality of the water and its toxicological load is mandatory to guarantee the consumption of pure water to citizens; besides, we need to expand access to pure water by planning actions able to treat contaminated water using environmentally sustainable technologies with the final aim to guarantee a low cost and microbiologically safe water. Concerning food demand, aquaculture is the fastest growing food producing industry globally. It accounts for 47% of fishery products, which is estimated to reach 62 % by 2030.
The project aims to face both sides of the coin by applying an integrated approach. On one side, we will develop new tools useful for eliminating pollutants. Different strategies will be adopted, all commonly sharing a low environmental impact. Fungi will be used to eliminate contaminant of emerging concern (CECs), with particular focus on antibiotics and some lipophilic compounds responsible of unpleasant taste on fish. On the other hand, potentially toxic elements (PTEs) such as dissolved As, Hg, Pb or Cd species will be captured by exploiting the use of iron, adsorbents derived from biomass and inorganic oxides and photocatalysts jointly linked to strengthen their efficiency.
The highest performing materials will then be supported on membranes or columns and will be tested in water for aquaculture or for reuse. In all sites, we will also assess the quality of water by monitoring CECs and PTEs in influent, effluent and post treated waters and by assessing the ecotoxicity and estrogenicity through the combination of different bioassays. The monitoring process will involve not only toxicological assays and chemical analysis using high-resolution techniques; it will also be combined with modelling processes aimed to fully assess the fate of pollutants.
