background
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

what we have a treatment facility
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

what we want a production facility
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

which way to go
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!
which technologies approaches
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
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!

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
on going projects
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
