About the Event

Water management underpins the very fabric of our daily lives, be it in the Netherlands or in Hong Kong. Insufficient fresh water supply in Hong Kong has been identified as a matter of concern. Water pipe leakage,
unmetered usage and incorrect metering accounted more than 15% of water loss. There is also an increasing
call for reclaiming water as well as improving wastewater treatment efficiency to promote water sustainability.

In this event, speakers from the Netherlands, Prof. Mirjam Blokker and Prof. Merle de Kreuk, will introduce the latest technologies to address the above challenges. Ir Prof. Irene Lo of the Institute for the Advanced Study and Prof. Joseph H. W. Lee, Senior Advisor to the President, Hong Kong University of Science and Technology (HKUST) will also lead the discussions with various speakers including delegates from the Government of the HKSAR on how to improve the overall urban water management system for a stronger water resilience policy in the future.

Prof. Dr. Ir. Merle de Kreuk

Sanitary Engineering, Delft University of Technology

Ir. Prof. Dr. Merle de Kreuk started her career in 1997 at IHC Holland, a shipyard for dredging vessels, where, with her colleagues, she worked on an innovative technology for the separation of contaminated soil and the clean sand fraction. This so-called jig-technology was later applied in many soil remediation projects. Prof. de Kreuk earned her PhD in environmental biotechnology at Delft University of Technology (TU Delft) in 2006.

 

During her doctoral studies, she collaborated with two other scientists to research and develop the aerobic granular sludge technology Nereda, currently brought to the market by Royal Haskoning DHV. The Nereda technology is characterised by the
granular growth of the biomass used in wastewater treatment. The use of this single-tank Nereda system makes wastewater treatment plants compact, energy efficient, and cheap. She won several prestigious awards for this technology and was a finalist with her fellow researchers for the European Inventor Award 2012 for the Nereda.

 

After earning her PhD, de Kreuk spent a few years bridging academic research with full-scale development of Nereda at Royal Haskoning DHV. Beginning in 2009, she worked for almost three years at the Dutch Water Authority, where she started a project on the application of Anammox in the mainstream of a wastewater treatment plant. While there, she was part of the “wastewater treatment plant of the future” studies, that led to the resource factory concept, in which technologies are developed and applied to produce energy-producing sewage treatment, as well as to secure the recovery of resources as nutrients and water. In 2011, she returned to TU Delft, where she focuses on granule formation processes (aerobic and anaerobic) and hydrolysis processes in anaerobic digestion. Furthermore, she is still interested in the product formation from waste streams by means of mixed microbial processes.

Ir. Dr. E.J. M. Blokker

Principal Scientist, KWR Watercycle Research Institute

Ir. Dr. Mirjam Blokker is a principal scientist on the drinking water infrastructure team. She is an expert in drinking water demand and developed the SIMDEUM model, which can be used to predict the demand for shower water, toilet flushing water, water consumption etc.

 

With this model, she also did research on the impact of flow speeds and residence times on water quality in the pipeline network and completed her Ph.D. on that topic in 2010. As an extension to this, Blokker carried out the research and implementation in designing the water network. In recent years, she researched the temperature in the pipeline network and the microbiological regrowth in the
network. In collaboration with her colleagues on the microbiology
team, Mirjam developed models for quantitative microbiological
risk analysis (QMRA) for collection, purification and in the distribution
network. Her knowledge of statistics came in rather handy for her
research on pipeline, valve, and fire hydrant failure. Blokker also stood
at the forefront of the introduction of the performance indicator for
inadequate supply minutes (OLM). Blokker owns a few Watershare
tools. She is a guest editor for Water, special issue on Water Quality in
Drinking Water Distribution Systems.
