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!

8 Where can this be achieved?
Hammarby Sjöstadsverk: A unique research and demonstration plant for wastewater treatment Applied (and basic) research Test and demonstration of new solutions Education Owned by KTH and IVL Contact:

9 A unique R&D facility Access to different wastewaters
Different aerobic/anaerobic treatment lines Relevant pilot scale for realistic results at affordable costs Mobile secondary/tertiary treatment modules Sludge handling/ biogas production System integration Competence

10 A platform for wastewater intelligence

11 On-going projects Removal of pharmaceuticals from the wastewater
Enhanced biogas production Anammox: cost-effective and environmentally friendly nitrogen reduction technology Minimizing the release of GHG by wastewater treatment The use of waste heat for stable temperatures during the biological treatment Bio-assimilation of nutrient in the biological step Membrane distillation for ultra pure water Complementary treatment with algae/CO2 sequestration Water reuse for non-potable and augmentation of potable water Online water quality monitoring
