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

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

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

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

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!

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.

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!

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
