Mark van Loosdrecht will receive Global Honor Award in Busan
Mark van Loosdrecht, professor at the Technical University Delft and principal scientist at KWR, will receive the Global Project Innovation Honor Award during the IWA World Water Congress in Busan, September 19. Van Loosdrecht and his colleagues from Hong Kong University of Science & Technology (HKUST) have been granted this award for a pilot of the SANI-system, a saline sewage treatment. The pilot is part of the saline water toilet flushing system, which is applied at the airport of Hong Kong.
Van Loosdrecht is one of the creators of SANI: the Sulfate reduction, Autotrophic denitrification, an Nitrification Integrated process. During this process, organics and nitrogen are removed from wastewater with the help of for example sulfate reducing bacteria. One of the main advantages of this novel process, in comparison to conventional biological nitrogen removal processes, is minimal sludge production. This saves energy. Furthermore, the number of pathogens in wastewater is reduced. These features make the SANI-system an economic and sustainable solution for sewage treatment. Currently, the system is being built on a demonstration scale in Hong Kong. Moreover, the SANI-system will be applied at saline wastewater in households.
