Laboratory for Water Quality and Treatment LTQE

The von Gunten group (LTQE) at EPFL was established in January 2011 and carries out research in close collaboration with the von Gunten group at Eawag (Drinking Water Chemistry Group at Eawag). Its research focuses mainly on oxidation and disinfection processes during drinking water and wastewater treatment. Furthermore, as the project leader of the cross-cutting Eawag project Wave21, Urs von Gunten established a strong link to the drinking water sector in Switzerland which lead to consulting of numerous water supplies and mineral water companies in Switzerland and abroad. This link is strengthened with the launch of the Eawag Competence Centre for Drinking Water.
