Wastewater treatment intelligence
The need for R&D facilities to master the future.
2
Background > 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

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

4
What we want: A production facilityOpportunities
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

Which way to go? 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 reuseNutrient 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 processesFlow 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!
