Christian Eschauzier doctorate 

Perfluoroalkyl compounds require new drinking water treatment methods

30 November 2013Research

Eschauzier is awarded his doctorate by the University of Amsterdam (UvA) for his research into the presence of perfluoroalkyl acids in drinking water. He carried out his research at KWR under the supervision of Principal Scientist Pim de Voogt.

Perfluoroalkyl acids (PFAAs) are substances that are frequently used in industrial and consumer goods – such as non-stick cookware – because of their water-, fat- and dirt-repellent properties, and their microbial and chemical stability. Current drinking water treatment methods have little or no effect in removing different PFAAs. For this reason, part of these substances, which are present in surface waters, can be found in the drinking water. Even though the concentrations measured in drinking water are below the existing acceptable level, water companies are already examining alternative treatment techniques capable of more extensive removal. Eschauzier discovered that ion exchangers are effective at removing PFAAs with so-called short alkane chains, while PFAAs with long alkane chains are more effectively removed using activated carbon.
