Wastewater treatment intelligence
The need for R&D facilities
to master the future.
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
2
What we have: A treatment facility
GHG out
Wastewater in
Energy in
Treated
Water out
Sludge out
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
3
What we want: A production facility
Nutrients out
Wastewater
in
Energy out
Water reuse
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
4
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!
5
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.
6
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!
7
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

 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
 …
