Global Honour Award for Van Loosdrecht

19 September 2012Networks

Mark van Loosdrecht, professor at Delft University of Technology and KWR’s Principal Researcher, receives the Global Project Innovation Honour Award during the 2012 IWA World Water Congress. He shares the prize with researchers from the Hong Kong University of Science and Technology (HKUST) for a pilot of the SANI system, which sustainably treats saline wastewater.

The pilot is part of the saline water toilet flushing system, which is being used at the Hong Kong airport and at other locations. Van Loosdrecht is one of the creators of SANI: the Sulfate reduction, Autotrophic denitrification, and Nitrification Integrated process. During the process, organics and nitrogen are removed from the water with the help, for example, of sulfate-reducing bacteria.

Less sludge and pathogens

One of the advantages of the SANI system compared to conventional wastewater treatment is that it produces less sludge. This saves energy. Furthermore, the number of pathogens in the water is also reduced. These features make the SANI system an economic and sustainable solution for the treatment of saline wastewater. The system is currently being built on a demonstration scale in Hong Kong and will be applied to saline wastewater from households.
