Description du projet
Traiter les eaux usées quand et où cela est nécessaire
Le traitement des eaux usées urbaines est fondamental pour protéger la santé publique et l’environnement. Le traitement décentralisé des eaux, résiduaires ou autres, est une alternative souple et durable aux grandes stations d’épuration. Cette solution pourrait contribuer à résoudre les problèmes de pénurie d’eau et de résilience au climat. Elle implique toutefois de localiser les usines de traitement des eaux usées sur le site de l’approvisionnement en eau, de la demande ou des deux. Le projet SARASWATI 2.0 financé par l’UE, entend identifier quelles sont les meilleures technologies disponibles et les plus abordables. Dans le prolongement du projet SARASWATI précédent (nommé en l’honneur de la déesse hindoue de la connaissance, de la musique, des arts et des sciences, ainsi qu’en référence au fleuve mythique sacré du monde indien dont on perdu la trace), des projets pilotes seront menés en Inde, pays qui souffre de la faiblesse de son niveau de traitement des eaux usées.
Objectif
The aim of SARASWATI 2.0 is to identify best available and affordable technologies for decentralized wastewater treatment with scope of resource/energy recovery and reuse in urban and rural areas. Further, it addresses the challenge of real time monitoring and automation. The previous SARASWATI project has shown that a number of decentralized wastewater treatment plants in India do not perform properly and that there are few plants that would meet the more stringent standards as those proposed by the Indian Government in 2015. Thus, in many cases not even CATNAP (the cheapest available technology narrowly avoiding prosecution) has been applied, leading to high pollution levels. The SARASWATI project therefore proposed to adopt the principle of BAT (best available technologies) in a more flexible way, adapting the definition of BAT to the local context, based on complementing the treatment efficiency with the costs of the treatment technology and affordability, and local context in the location of application. This will allow to identify BATs with more stringent standards if required and suitable for the location. Thereby, ten pilot technologies in 7 Indian States demonstrating enhanced removal of organic pollution (BOD, TSS), nutrients (particularly Nitrogen), organic micro-pollutants and pathogens have been proposed (WP1). Further, all pilots allow for resource recovery contributing to the principles of a circular economy and will undergo a comprehensive performance assessment (WP2) complemented by an extended sustainability assessment informed by recent ISO standards (WP4). This will allow identification of BATs for the Indian context. In addition, suitable automation and control strategies will be tested and recommended, taking into account the presence of operators and their level of knowledge and expertise (WP3). Finally, WP5 is dedicated to dissemination and exploitation of results. The consortium is comprised of a well-balanced EU-Indian team of 17 partners.
