LaViSO – Laboratoire Vivant du Sud-Ouest, is the the French Southwestern Living Living Lab developed in the framework of TWIST project.

LaVISO Living Lab will work to improve the quality of wastewater treatment, reduce the energy consumption associated to wastewater treatment, limiting treatment costs and producing secondary resources (energy, fertilisers, irrigation…) developing co-creation innovation processes in:

• Collective sanitation and waste water treatment;
• On site sanitation system;
• Asset management;
• Non-conventional water use and circular economy;
• Innovative public procurement.

LaViSO Living Lab is constituted by three entities where different tests will be developed: IFTS, Institut de la Filtration et des Techniques séparatives (Institute of Filtration and Separation Techniques), OIEau, Office International de l’Eau (International office for Water) and UNILIM, Université de Limoges (University of Limoges).

The different tests being developed in LaVISO Living-Lab

IFTS is testing different processes to create, from the effluents of the Wastewater Treatment Plant, water whose quality will allow uses adapted to the creation of islands of freshness. This test is being developed in partnership with MARTEAU project where IFTS is the leader. The project MARTEAU is about Alternative Mobilisation of Territorial Resources in treated wastewater.

OIEau is carrying out two pilot tests: 1) For the early detection of the cavitation phenomenon of a pump via the monitoring of a pump’s power supply current and 2) Test of a drinking water process used as a tertiary treatment step for the reuse of treated wastewater.

UNILIM, through its Laboratory PEIRENE et notamment de l’Equipe Micropolluant et Procédés – FST (Micropollutant and Processes Team) studies major contaminants/elements in the environment and in water treatment plants, both waste water major quality parameters and organic and inorganic trace elements are considered.

Pereine has a profusion of techniques and materials for students in its laboratories and pilot rooms that are made available for innovation research projects. These allow both research and the setting up of small-scale test benches on questions and evaluation of the mobility of contaminants in complex environments.
