About Prof. Mark van Loosdrecht :

Biography: Mark van Loosdrecht is Professor in Environmental Biotechnology at Delft University of Technology, The Netherlands. He graduated from and did his PhD research at Wageningen University. His PhD topic was a combination of microbiology and colloid chemistry. He was appointed at Delft in 1988 and became Full Professor in 1998. His research is characterized by the combination of scientific understanding of complex systems and development of new processes. His scientific interests are mainly related to biofilm processes, nutrient conversion processes and the role of storage polymers in microbial ecology. In particular, he is interested in new processes related to wastewater treatment and resource recovery. His research has resulted in several processes currently applied on full scale such as the Sharon process, Anammox process and Nereda process. He is active member of the International Water Association (IWA) and past chairman of the Biofilm and the Nutrient removal specialist groups. He was Editor-in-Chief of Water Research (2011-2019). He obtained several prizes for his work, including the Lee Kuan Yew Singapore Water Prize, the Stockholm water prize and the IWA Grand Award. He is member of the Royal Dutch Academy of Arts and Sciences and the Dutch, USA and Chinese Academy of Engineering. He was awarded a knighthood in the order of the Dutch Lion and a honorary doctorate by ETH Zurich and U. Gent. He has co-authored over 750 scientific papers, has 20 patents and has supervised over 75 PhD students.

Abstract
Development of Aerobic Granular Sludge Technology: Municipal wastewater treatment has for a long time been depending on bacteria growing in the form of flocculent sludge. The large clarification basins needed for the solid liquid separation of the slow settling flocculent sludge gives the technology a large footprint. Higher settling rates of the biomass can be obtained by growing bacteria in the form of granular sludge. Understanding the governing principles of morphogenesis of microbial aggregates/biofilms forms the basis of the design of granular sludge reactors. The technology has been scaled up and is currently marketed as Nereda technology. Within the context of future resource recovery from wastewater currently the characterization and recovery of microbial EPS is under investigation. The EPS from granular sludge is currently in a scale-up phase to be brought on the market. This presentation will discuss the development of the nereda technology and the potential of EPS as a new resource for materials production.

 Participation is open to all interested people.
