4. Clean water

Due to the worldwide economy and growth in population there is a strong increase in the demand for clean and affordable water. Water is not only needed for ensuring human health (drinking water, sanitation) but also for industrial activity and agriculture. The water challenge is complicated as it is intrinsically linked to two other big challenges, energy and food security.

 

New technology is needed to ensure water reuse, reduce energy consumption, or energy production and enables the reuse of the components present in water. Only recently, nanotechnology is being explored for application in the water technology area. Current water technology is not adequately equipped to cope with the big challenges of energy and food security. This technology focuses primarily on water purification only and consumes a great deal of energy.

Breakthrough innovations

Given the big challenges and the innovative opportunities, nanotechnology seems to be well positioned to deliver breakthrough innovations. Nanotechnology makes it possible to convert contaminated surface water in water of the desired quality, for example. Membranes filter dust particles, micro-organisms and organic material from the water. Nanotechnology enables the production of pores in these ultra-fine membranes with even greater precision, so that almost 100 percent of micro-organisms is removed.

This theme contains the following programme:

4A Nanotechnology in water applications

This research aims to develop nanotechnology-based solutions for the efficient and economical production of clean and healthy drinking water from different sources. These solutions not only recognise visible and previously known contaminants but also unknown ones in particular. The applications are mainly in water desalination, water disinfection, water reuse and water safety. Nanotechnology makes it possible to convert contaminated surface water in water of the desired quality, for example. Membranes filter dust particles, micro-organisms and organic material from the water. Nanotechnology makes it possible to produce pores in these ultra-fine membranes with even greater precision, so that almost one hundred percent of micro-organisms is removed.
