Opis

This study aimed to optimize the electron donor supply in sulphate reducing bioreactors treating sulphate rich wastewater. Lactate and slow release electron donors, such as carbohydrate based polymers and lignocellulosic biowastes, were used for biological sulphate reduction in different bioreactor configurations: the inverse fluidized bed, sequencing batch and batch reactors. The reactors were tested under steady-state, high-rate and transient-state feeding conditions of electron donor and acceptor, respectively.

O autorze

Luis Carlos Reyes-Alvarado (born in Córdoba, Veracruz, Mexico) obtained his PhD in Environmental Technology. He joined the Universidad Veracruzana (Mexico) where he obtained the degree of Chemical Engineering and further a Master in Food Science and Technology, after which he received an ALFA grant within the SUPPORT (Sustainable Use of Photosynthesis Products & Optimum Resource Transformation) project at the TU Graz (Austria).
Luis developed and defended his PhD thesis through the Erasmus Mundus Joint Doctorate Programme in Environmental Technologies for Contaminated Solids, Soils and Sediments (ETeCoS³) on December 16^th, 2016. His research was focused on the optimization of electron donor supply to sulphate reducing bioreactors treating inorganic wastewater rich in sulphate and carried out at different institutions: the UNESCO-IHE (Delft, The Netherlands), the Universidad Veracruzana (Veracruz, Mexico), the INRA-Laboratoire de Biotechnologie de l’Environnement (Narbonne, France) and the University of Cassino and Southern Lazio (Cassino, Italy). Luis' main interest is understanding the engineering aspects of biological processes, resource recovery from waste and the development of eco-technologies for waste remediation.
