The Congress will host international experts, including:

  • Veronica Manfredi, from the European Commission DG zero pollution and quality of life on air, water & industrial emission;

  • Urs von Gunten, Swiss environmental chemist and professor at EPFL.

The experts will present and discuss the latest developments on new European and national directives and regulations and knowledge and technologies for the development and application of ozone-based processes and other advanced oxidation systems for:

  • Environmental protection and human health (water, gas, soil, and waste).
  • Industrial production and treatment: cellulose and paper, food, electronics, chemicals, and more.
  • Medical therapy.

By participating in the Congress, attendees can meet experts and delve into the main trends of the sector, discover innovative technologies, and develop business opportunities with the over 400 expected participants.


As part of the LE2C initiative, they will participate in the conference "Ozone in the management of the integrated water cycle" to present the work of the Working Group on "Emerging and Priority Micro Pollutants" (GdL-MIE).

De Nora Industries, a LE2C member, will attend the Congress with an exhibition stand and will be involved in several conferences with their technical speakers.

In addition, among the planned technical visits, Lariana Depur S.p.A. - a LE2C member - will allow interested participants to visit their wastewater treatment plant on Friday, July 7th, 2023. The plant uses ozone for various applications, such as color removal, COD reduction, and sludge reduction through an ozonolysis process.
