Clean Water - Nanotechnology Theme 4
4. Clean Water
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.
The following programme falls under this theme:

4A Nanotechnology in water applications
The removal of contaminants from water is a technological and societal priority for the coming decennia. Filtration with high porosity, thin and isoporous membranes will be the technical solution of choice for particulate matter such as viruses and nano-particles. Understanding the behavior of such particles in confined space is a pre-requisite for designing and fabricating new membranes. Dissolved matter such as pharmaceutical and other harmful low molecular weight chemicals need to be catalytically destroyed with catalysts of well-ordered 3D micro- and nano-topology embedded in designed devices. The program is characterized by an integrative effort to start with a nanotechnologybased concept and integrate it into macro applications. This is realized by bringing together scientific and engineering expertise from academia, institutes and industry.
This program aims to perform a breakthrough step in water related technologies based on bottom-up and top down nano-engineered materials. Industrially and health relevant issues will be adresses in the following three clusters:
· Nano- and microfabrication for molecular separations
· Nano-to-Macro integration for catalysis applications in water treatment
· Nano-particles in aqueous confined space
