HaV Pharmaceuticals - Systems for the purification of pharmaceutical residues and other priority persistent substances
Project summary Pdf, 290.9 kB.

R3Water - Demonstration of innovative solutions for Reuse of water, Recovery of valuables and Resource efficiency in urban wastewater treatment
Project summary Pdf, 437 kB.

Converting Active sludge facilities to MembraneBioReactor systems
Project summary Pdf, 427.1 kB.

To be able to predict wastewater parameters that are difficult to measure on-line by using parameters that are easy to measure on-line.
Expected benefit:
No or a minimal amount of time with un-functioning sensors, which is extremely important both for surveillance but mostly if the parameters are used for automatic plant control including regulation of chemical and energy use.
Project summary Pdf, 348.3 kB.

Reuse of treated wastewater for non-potable use
Goal: To optimize treatment processes and systems for non-potable water reuse applications worldwide, to assess treatment processes in terms of sustainability to achieve the lowest life cycle costs now and in the future, to achieve the best possible micropollutant reduction, and to create treatment systems that can be adapted to local and regional requirements and conditions.
Expected benefit: The project will develop sustainable solutions to reclaim treated wastewater for urban, agriculture, recreation, industry, and groundwater recharge uses.
Project summary Pdf, 304.8 kB.

More efficient biogas production
Goal: Increased biogas production by utilizing more of the organic substances contained in the produced sludge.
Expected benefit: Substantially increased biogas production at municipal treatment plants.
Project summary Pdf, 440.7 kB.

Anammox technology: nitrogen reduction
Goal: Increase knowledge of nitrogen reduction systems of supernatant from dewatered sludge at municipal treatment plants.
Expected benefit: Research and development efforts can lead to a more cost-effective and environmentally friendly nitrogen reduction technology.

Finished Projects

Silver nanoparticles in WWTP
Project summary

Membrane distillation for treatment of effluents and production of clean water
To test and optimize (from a life-cycle perspective) membrane distillation for treatment of water streams.
Expected benefit: To show the potential of membrane distillation as alternative or complement to existing separation technologies from a technical and system perspective. Project summary

Small-scale biogas upgrading technology
To test and further develop a technology for small-scale biogas upgrading. Expected benefit: Enable cost-efficient biogas upgrading even at smaller scales.

Reduce the greenhouse gas emissions from Swedish wastewater and sewage sludge management
To provide new knowledge on the green house gas (GHG) emissions from wastewater and sludge processes, and to provide good decision support on suitable combinations and operation for such processes to minimize GHG emissions.
Expected benefit: Decreased greenhouse gas emissions from the treatment of wastewater, and especially from the treatment of reject water and the handling of the sewage sludge.
Project summary

Removal of pharmaceuticals from the wastewater
Treated municipal wastewater shall not contain harmful proportions of chemical substances.
Expected benefit: Further decreased risk for long term negative effects on the environment.
Project summary

Energy and resource management facility
To investigate whether a conventional wastewater treatment plant can be run with high organic load, short sludge age and nutrient removal by 100% biological assimilation. Expected benefit: The proposed project will lead to imply that treatment plants will produce more energy (through production of biogas from sludge digestion) than they consumed to treat wastewater. The plants will have a more stable and safe operation. Low or no usage of chemicals.
Project summary

ITEST - energy efficiency and improved wastewater treatment by use of waste heat
To stabilize temperatures in the biological treatment step through the use of waste heat and to lower the temperature in the return flow for power generation.
Expected benefit: Improved biological wastewater treatment even at low temperatures and increased efficiency of power plants.
