Treatment of micropollutants in wastewater: results of the Micropolis study


Conducted at the Sophia Antipolis wastewater treatment plant in France, the only one to treat micropollutants in the Rhone-Mediterranean basin, the Micropolis study aims to evaluate, in real conditions, the ozonation system’s effectiveness in treating micropollutants in wastewater. The study is composed of two parts: Micropolis-Procédés and Micropolis-Indicateurs.

The first study, Micropolis-Procédés, was conducted by the IRSTEA between 2013 and 2016 in collaboration with SUEZ and with the financial support of the Rhone-Mediterranean and Corsica Water Agency. The results of the study conclude that the ozonation facility is effective in the treatment of emerging substances.

The second study, Micropolis-Indicateurs, carried out by SUEZ in collaboration with INERIS, TOXEM, IRSTEA, BIOMAE, the University of Bordeaux and the Syndicat des Bouillides with the support of the French Agency for Biodiversity and the Rhone-Mediterranean and Corsica Water Agency, focuses on the characterization of the toxicity of wastewater. It also offers a methodology to better target reductions at source.
