Marta Carballa

Marta Carballa is Associate Professor in the Department of Chemical Engineering at the University of Santiago de Compostela (Spain). She is Chemical Engineer and obtained her PhD in Chemical and Environmental Engineering at the same university in December 2005.

During the first years (2001-2005), her research has focused on the removal of organic micropollutants (mainly pharmaceuticals, cosmetics and estrogens) in sewage treatment plants (STPs) and during sludge anaerobic digestion. During the research stays in Chile and Belgium (2006-2009), her research experience was extended to the removal and recovery of nutrients (mainly nitrogen and phosphorus). Her current research interests include: anaerobic (co-) digestion processes, analyzing not only the technical aspects but also the study of the microbial community in order to relate the digester functionality with the structure of the microbial community, and the identification and quantification of the removal mechanisms of organic micropollutants in biological wastewater and sludge treatment processes.

Emmanuel Van Houtte

Emmanuel Van Houtte studied at the Ghent University where he graduated as a geologist in 1984. He has been working for the Intermunicipal Water Company of the Veurne Region (I.W.V.A.) since 1992 where he was hired to develop sustainable groundwater management in the dunes. In that context, he led different projects such as sudies at the Torreele UF/RO waster reclamation plant. The most recent trials at that plant are related to the usage of willows to combine treatment of RO concentrate and biomass production.

His other responsibilities within the I.W.V.A. are quality management (both drinking-water and process waters), the dunes (includes groundwater monitoring and ecological issues), environmental issues in general and research and development.

He presented on many occasions about the results of the pilot tests, the performance of the full-scale plant and the infiltration project and was invited on several expert meetings and consultations concerning reuse. The Torreele reuse/ St-André infiltration project was part of the Aquarec (FP5) and RECLAIM (FP6) projects and currently IWVA participates in the DEMOWARE (FP7) project all sponsored by the European Commission.
