Precursor of mathematical modeling processes of water treatment in the 80's, his pioneering studies laid the foundation for all the work that has been developed further on this subject in recent decades
George A. Ekama, PhD, has 35 years research experience into activated sludge systems at the University of Cape Town, where some of the original biological N and P removal kinetic simulation modelling research was done in the 1980s, which found its way into activated sludge models.
He has published over 150 research papers and 4 International Water Association (IWA) Scientific and Technical Reports (STR). He has been visiting Professor at Virginia Tech, University of Padua and the UNESCO- IHE in Delft, teaching graduate courses on wastewater treatment. He regularly teaches courses for local authorities and industry, both nationally and internationally, such as for the Hong Kong Government in 1999, 2003 and 2008, and Beijing Water Corporation in 2006.
He is one of a few environmental engineering professors listed on Thomson's ISI Highly Cited website (http://www.isihighlycited.com). He is co-author and co-editor of the recently published (2008) internet learning course called "Biological wastewater treatment - Principles, modelling and design" sponsored by the UNESCO-IHE in Delft and the IWA, which includes a book, down-loadable course notes and video-filmed lectures.
