Research axes

REVERSAAL’s research aims to conceptualize the wastewater treatment plants of the future (water resource recovery plants), and to continue its integration into the sewer network-treatment plant- surface water-soil continuum. Engineers and researchers advance knowledge and develop recommendations in terms of design, sizing, operation and optimization of processes and systems. They develop innovative methods and tools that are transferable to operational actors (both public and private).

The work of REVERSAAL is divided into four main areas, which deal with the following main scientific questions:

Axis 1

Reduce emissions

Axis 2

Reuse water

Axis 3

Recovering and enhancing resources

Axis 4

Digital innovation

Facilitator :



Pascal MOLLE





Evaluate, develop and optimise innovative, compact, energy-saving processes.

Master the processes

Adapt the design and operations.

Develop treatment processes, including nature-based solutions, and associated control strategies, to produce water adapted to different uses and different territorial contexts (southern countries).

·         Integrate process aspects into multi-criteria decision support tools

Improve the relationship between organic matter composition / energy production capacity, and colloid-organic matter interactions

Optimise recovery processes (carbon capture, nutrient and metal recovery, etc.)

Secure, reliable and share data (towards FAIR and open data), including data acquired online.

Reinforce predictive approaches from mechanistic modelling to apprenticeship methods

Since January 1, 2018, REVERSAAL has been associated in a joint research cluster for Water and Waste – RESEED – with the DEEP laboratory of INSA. We have built our scientific program together with INSA DEEP within the framework of the common research group RESEED. This scientific cooperation between the two groups will increase the thematic critical mass, promote knowledge transfer and regional anchoring, thus increasing the visibility and attractiveness of INRAE and INSA. In practice, this cooperation will allow to study the Water resource recovery facilities (WRRF) using new methods for sludge characterization (methane potentials, geochemical characterization, mechanistic approaches…), methods for estimating uncertainties and new modeling approaches; it will also contribute to the emergence of new approaches to urban water management.
