Usually presented as a tertiary treatment downstream of biological treatments, advanced oxidation by solar energy improves the sanitary quality of an effluent at a controlled energy cost. These processes are considered to provide a response to the necessary removal of micro-pollutants such as pesticides, drug residues, effluents from the chemical, agrochemical and petrochemical industries. Advanced oxidation processes also provide a solution in the field of disinfection by eliminating pathogens. A major application is part of the basic trend of reusing treated wastewater (REUT). While France, following the decree of 2 August 2010, only recently allowed the exploitation of this resource, this option is being implemented in several European countries, including Spain, and also and intensively in geographical areas under severe water availability constraints such as Israel or Australia. The literature and the number of French and European research units working on the principle of advanced oxidation processes (POAs) are very abundant, but are much less important for experiments conducted under real irradiation conditions. Nevertheless, it is the preferred source of radiant energy if one's wishes to develop processes that are consistent with the principle of sustainable development.

The general objective of the work to be carried out during the postdoctoral contract is thus to contribute to the continuation of the research/development carried out by the SHPE team of the PROMES laboratory on advanced oxidation processes based on the direct use of solar radiation and with disinfection as an objective. The aim is to improve the sanitary level of effluents from wastewater treatment plants before their discharge in order to be able to consider their reuse, particularly for irrigation purposes. The process is based on the use of highly reactive radical species that can be directly produced from solar energy by photonic and/or thermal activation.

Working on extremely complex effluents, it is necessary to have a sufficient experimental database to be able to identify the performance of this type of treatment, which is expressed in terms of the population of pathogens before and after treatment. One of the objectives is to continue the measurement campains on existing installations (working under natural solar radiation) in order to acquire a set of data representative of performance under various irradiation conditions. The second objective is to propose, on the basis of these data, a necessarily macroscopic and simplified modelling approach taking into account the composition of the water matrix to be treated. The third objective is to propose, based on previously acquired knowledge and previously validated behavioural laws, significant evolutions of existing installations in order to be able to consider a change of scale.


- Experimental work on existing prototypes.
- Design and optimization of a new reactor/process allowing a change of scale.


Post-doctoral student mastering experimental practices.
Knowledge in process engineering/chemical engineering.
Expected experience in the field of disinfection of liquid effluents.

Work Context

The laboratory Processes, Materials and Solar Energy (PROMES UPR CNRS 8521) is a research unit of the CNRS. It is composed of nearly 150 people, 90 of whom are permanent. It is structured around two main research axes: materials and extreme conditions; energy conversion, storage and transport. The SHPE team develops its activity within axis two through these two research themes: (i) waste recovery and high-temperature solar energy storage; (ii) advanced solar oxidation for effluent detoxification. It is on this second point, directly linked to the proposed postdoctoral contract, that it also contributes to priority axis 4 "solar ecotechnology", which defines the objectives of the partners of the Solstice Labex renewed for a period of 5 years starting in January 2020.
