1. Wastewater treatment intelligence The need for R&D facilities to master the future.

2. Background  Clear link to wastewater treatment
> 2 billion people have water shortage
Diseases due to bad water quality
Millions lack proper waste-water treatment
Deterioration of quantity and quality of natural water systems
Agriculture uses 2/3 of the water that is consumed
Increasing water demand for industrial growth
New regulations (e.g. EU)
Use of chemicals in water treatment  <1% recycling
Request of use of renewable energy sources
Sustainable growth and development
 Clear link to wastewater treatment

3. What we have: A treatment facility
Problems/Challenges
The water sector is a major energy user
GHG emissions
Treated water is not used
Outflows may contain pollutants, viruses, pathogens etc.
Sludge seen as a problem
GHG out
Sewage
works
Treated
Water out
Wastewater in
Sludge out
Energy in

4. What we want: A production facility
Opportunities
Waste as resource
Net energy production
Nutrients recovery/reuse
Improved treatment
Water reuse (non-potable reuse/augmentation of potable water)
Sustainable production of energy and resources
Market opportunitets
Energy out
Nutrients out
Sewage
works
Wastewater in
Water reuse

5. Which way to go? New approaches and concept shift a necessity!
e.g. forecasted energy usage by the water sector [%]
(British Council for Science & Technology 2009)
New approaches and concept shift a necessity!
This implies R&D and market opportunities!

6. Which technologies/approaches?
Resources efficient treatment technologies
Soft sensors | Anaerobic treatment | Anammox | Side stream treatment | Advanced membrane technologies | Process control and modelling | …
Technologies for recovery and reuse
Nutrient recovery from ashes | Nutrients in sludge/sorbent | Water reuse/ Irrigation (nutrient rich effluent) | Industrial water | Potable water | Augmentation of potable water | Removal of pharmaceuticals, pathogens, viruses etc. | Online water quality monitoring | …
Energy production & carbon neutral/negative processes
Flow separation | Increased sludge production | Enhanced Sludge digestion (also co-digestion) | Sewage digestion | Gasification/burning | Microbiological fuel cell | Algae treatment | …
Key ingredient: Combination and system integration with a holistic perspective of these different technologies/approaches to meet different requirements.

7. What other ingredients are needed?
Stakeholder involvement (companies, authorities, research organisations, associations, sewage plants, etc.)
Basic and applied R&D partners
Innovation Platform
Demonstrators
Approach and Knowledge Transfer Networks
Improving skills base/Education
Public dialogue/involvement
International co-operation and collaboration
 Optimal if you could find all these at the same location!
