Indoor Water

The aim of for this project is new innovations in and concepts for indoor water systems which include water systems providing solutions for international water scarcity.

Household water circulation and treatment systems will be developed that meet future requirements for drinking water quality by adapting and developing existing leading edge technology to obtain:

  1. Super high quality drinking water from different mains delivered water qualities
  2. Low energy technologies for recycling grey water within the home
  3. Efficient collection and treatment of wastewater in-home by combining biological processes with nanotechnology.

New membrane technologies, including nanofilters, can be used to remove substances from raw water sources (van der Bruggen and Vandecasteele 2003). Systems will be tested in our laboratory pilot scale reactors. Nanotechnology will be used to tailor surfaces of membranes and nano particles with desired properties (Savage and Diallo 2005). Alternatives to generally used disinfection methods will be tested, such as photocatalysis on titanium dioxide coated surgaces or other catalytic surfaces (Adesina 2004, Duran et al 2007). For the wastewater treatment, small scale MBR systems will be investigated (Abegglen et al 2008) as these systems are particularly suitable for small scale systems with highly variable flow conditions. An assessment of ultra/nanofiltration and membrane-supported photocatalysis, as well as separation and recycling systems, will be carried out at laboratory and demonstration scales.
