  1. Wastewater treatment intelligenceThe 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 • Sustainablegrowth 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. • Sludgeseen 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 • Improvedtreatment • Water reuse (non-potable reuse/augmentation of potable water) • Sustainable production of energy and resources • Market opportunitets Energy out Nutrients out Sewage works Water reuse Wastewater in

  5. 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 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: www.sjostadsverket.se

  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 • …
