Hans Cappon

Professor Water Technology

Dr Hans Cappon is Professor of the Water Technology Research Group within HZ University of Applied Sciences. Over his years at HZ he has worked on many water technology projects including; NEREUS (New Energy and Resources for Urban Sanitation), FRESH4Cs (Alternative Fresh Water resources for Coastal Areas), IMPROVED (Integrale Mobiele Processwatervoorziening voor een Economische Delta) and was involved in the operations of the Dow/Evides pilot within the EU-FP7 E4Water project. Aside from his work with the research group he is also a lecturer in water treatment at HZ at BSc and MSc level and a lecturer and researcher in Urban Systems Engineering in the department of Environmental Technology at Wageningen University in the Netherlands. Hans has over 20 years of experience in scientific research, also from his previous work at TNO and the Catholic University in Leuven. Hans’ main expertise is modelling and optimization of dynamic systems with a focus on water treatment and energy systems during the last 10 years. In 2014 he completed his PhD entitled “Numerical and experimental design of ultrasonic particle filters for water treatment.” He achieved his Master in Biomechanical Engineering at the Technical University of Eindhoven in 1997.

Terneuzen The Netherlands


The Water Technology Research Group is a partner in the European Union Horizon 2020 programme for the research project AquaSPICE. AquaSPICE aims at Advancing Sustainability of Process Industries through Digital and Circular Water Use Innovations.

Water is used during stages of production processes in most industries. It is estimated that 20% of all fresh water consumption globally is used by industry. Innovation in water treatment can bring closed loops to almost 100% efficiency for important industrial water users by recovering and reusing resources.

Water scarcity is a reality for some of Dow locations around Europe. Dow is seeking opportunities to reduce the fresh water intake in the different production sites by reusing water streams. The water streams will be treated by technologies to reuse them again in the processes. Therefore, a pilot will be operated, which consists of containers with different water treatment technologies.

The pilot will be operated at Dow Terneuzen, Dow Böhlen, and BASF Antwerpen. At each location, different water streams with different treatments will be tested. This case study is a collaboration between Dow (Terneuzen and Böhlen), Ghent University, Evides Industriewater, RWTH Aachen University, and HZ University of Applied Sciences.

Additionally, the focus will be on intelligent water management. A water cyber-physical-system will be created with a measurement network of real-time sensors and a model will be constructed where decisions can be made.

Hans Cappon, Emma McAteer and Lies Hamelink, from the Water Technology research group, are working on the AquaSPICE project. They are responsible for supporting the operational work of the pilots at Dow Terneuzen and Dow Böhlen, as well as participating in the data analyses and evaluation of the results.

The project Aquaspice has received funding from European Union's Horizon 2020 research and innovation programme under grant agreement No 958396.
