Fight against new pollutants in water

Changing consumer habits have resulted in the appearance of new pollutants in water. These micro-pollutants, even on a scale of traces, are becoming one of the main issues facing local authorities and industry in the protection of the receiving ecosystems. As a pioneer in this field, for several years, SUEZ has been running research and development studies in its Paris-based expertise and research centre, the CIRSEE (international centre 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 millions population-equivalent today and more than 2.5 million in 2018, from those emerging contaminants with SUEZ processes built around «ozonia ® » ozone systems »

Collaboration with top international experts

SUEZ is addressing the challenge posed by these micro-pollutants with the best French and international teams specialized in the biological effects of exposure to micro-pollutants. With the help of teams from universities, SUEZ is looking into the effectiveness and the benefits for consumer health of its plans to prevent sanitary risks.

Effective collaborative innovation in Lausanne, Switzerland

In 2011, SUEZ launched a collaborative innovation programme with the city of Lausanne to enrich its expertise in the realm of micro-pollutants. The programme 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 world premier helped SUEZ to win the contract with the city authorities for an unprecedented system that totally protects Lake Geneva. On 1 January  2016, Switzerland became the first country in the world 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.

“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.”

An annual seminar for Ph.D students

Every year, SUEZ, the University of Lorraine (France) and Bonn University (Germany) co-organize the 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.

A forum for discussions and meetings

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 major issue can be discussed.

The 2016 SUEZ Water and Health Award

Thierry Mallet, Director of Innovation, Marketing and Industrial Performance, handed over the SUEZ Water and Health Award, and a check for €1,500 to Caroline Delaire, University of California, Berkeley, USA for her thesis: “From arsenic and bacteria removal to household behaviour change: How to improve access to safe water in West Bengal, India”.

The presentations were judged according to four criteria:

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