Sweden Water Research conducts research into water and develops new, effective solutions to meet the future challenges facing the water services industry.
We create, run, participate in and initiate projects that seek out suitable partnerships, with the ultimate aim of increasing knowledge of successful methods for the development and climate change adaptation of the cities of the future. Projects within Sweden Water Research are run in close collaboration with the owner municipalities and will, in either the short or the long term, benefit day-to-day operations.

focuses on improving the operation of anaerobic digesters treating blackwater. Through targeted measures, monitoring and testing in both the Netherlands and Helsingborg, the project aims to achieve more stable and efficient digestion, with reduced sludge washout and improved management of floating sludge.
MABR (“membrane aerated biofilm reactor”) is a relatively new technology for wastewater treatment that allows for increased treatment capacity in existing volumes.
A cross-industry initiative has been created to reduce nitrous oxide emissions from Swedish wastewater treatment.
In order to achieve climate neutral transportation, different types of fuel such as electricity, biogas and hydrogen are needed.
Rising electricity prices and the accelerating climate crisis make energy efficiency a high priority for Swedish wastewater treatment plants.
New environmental permits for wastewater treatment plants tend to demand lower effluent concentrations than before.
Many municipal wastewater treatment plants are facing expansion and reconstruction. Lack of space and requirements for sustainability mean that compact, resource-efficient, environmentally friendly and cost-effective solutions are in demand. This project is about investigating a new biofilm process, with a bio-based carrier, to assess whether this process can be a viable alternative in future wastewater treatment plants.
Previous studies show that the potential to make municipal wastewater treatment plants (WWTPs) more energy efficient is great. The largest energy use at WWTPs is found in the aeration of the biological processes in the wastewater treatment.
This was Elin Ossiansson's PhD project. Elin was an industrial PhD student working for Sweden Water Research, VA SYD and Chalmers University of Technology.
This is Ashley Hall’s doctoral thesis. Ashley is an industrial doctoral student from Sweden Water Research through Lund University.
Major investments will be required in the next few years to deal with aging infrastructure, population growth, urbanisation and new emission requirements at municipal wastewater treatment plants (WWTPs). These investments are preceded by evaluation, design and optimization, which in turn require access to good data to provide security in the decisions made and to ensure cost-effective solutions.
Within this project, a method for developing digital twins at WWTPs will be developed, including real time process simulation and data validation.
