Fighting the new pollutants in water

Changing consumer habits have resulted in the appearance of new pollutants. These micro-pollutants, even on an even on a scale of traces are becoming one of the main issues facing local authorities and industry in the protection their respective ecosystems. As a pioneer in this field, we’ve been running research and development studies in its Paris-based expertise and research center, the CIRSEE (international center of research into water and the environment).

‘ Micro-pollutants are the key challenge of tomorrow’s wastewater. We are very proud to protect 1.5 million population-equivalent today and more than 2.5 million in 2018, from those emerging contaminants with SUEZ processes built around «ozonia ® » ozone systems ‘

Discover our collaboration with top international experts

In 2011, we launched a program with the city of Lausanne to enrich its knowledge of micro-pollutants. The program tested a number of innovative solutions, and in particular the combination of two leading-edge technologies: oxidation by ozone and absorption on a pulsed reactor of powdered activated carbon. This game changing technology helped us win the contract with the city authorities for an unprecedented system which totally protects Lake Geneva. On 1 January 2016, Switzerland became the first country to introduce legislation on the treatment of the micro-pollutants present in wastewater. In May 2016, EPURA, a limited company belonging to the City of Lausanne, supported by the engineering consultants BG Ingénieurs Conseils SA and Holinger SA, chose SUEZ and its Swiss partner TECHFINA to build the facilities to treat wastewater, micro-pollutants and purification sludge at the Vidy purification station, which serves the Lausanne region.

We encourage external research projects

The water and health seminar Laboratory-SUEZ
“The Water and Health seminar co-organized by SUEZ is a forum for the discussion of questions related to water and the possible solutions. The seminar is attended by students and academic and industrial researchers of international renown.”

We sponsor an annual seminar for Ph.D. students

Every year, SUEZ, the University of Lorraine (France) and Bonn University (Germany) co-organize an international Water and Health seminar for Ph.D. students. The event provides a forum for students from all over the world to discuss the results of their research (pollutants of hydric origin, epidemiology, microbiology, the sociological aspects of crisis management, etc.) with leading international scientists. At each seminar, the scientific committee awards the SUEZ prize to the student whose work makes the best contribution to the improvement of the sanitary quality of water.

We provide a forum for discussion 

The seminar provides a forum where students can share their experiences and projects with other young people, dialogue is encouraged between different generations of scientists and the disciplines related to this issue. 

The 2017 SUEZ Water and Health Award 

Loïc Voisin, Director of Innovation, Marketing and Industrial Performance, handed over the SUEZ Water and Health Award, and a check for €1,500 to Terica Sinclair from the University of Twente (Netherlands) for her work: Cationically modified membranes for the removal of waterborne viruses.

The presentations were judged according to four criteria:

  • the scientific approach,
  • innovation,
  • possible applications to water,
  • the quality of oral communication.
