New project about stormwater treatment
ReCircWater addresses a pressing challenge for the South Baltic region: how to treat, manage and reuse urban stormwater so fewer pollutants reach the Baltic Sea and more water can be put to beneficial use.
Congratulations Ellinor!
Today, Ellinor Frank successfully defended her thesis ”Microbial Source Tracking for Bathing Water Quality Assessment: E. coli and Bacterial Communities in Coastal Environment”.
Faster and smarter water quality control using AI
Industrial PhD student Isabel Erb describes in a new article in Water Research X the work on faster and smarter water quality control using AI.
Visit at Värpinge wetland from Nacka Municipality
A few weeks ago, colleagues from the Unit for Strategic Climate and Environmental Work at Nacka Municipality came to visit.
The initiative’s first report published
During late autumn 2024 and spring 2025, the first project of this initiative was carried out with co-funding from the Impact Innovation program Water Wise Societies.
Measurement of nitrous oxide emissions at the Käppala Association
Käppala Wastewater Treatment Plant (WWTP), located on Lidingö in Stockholm, is Sweden's third largest wastewater treatment plant and receives municipal wastewater from approximately 554,000 population equivalents (2024). The plant is located underground, which means that all process air can be collected and directed to a chimney.
We can now begin sampling the wetland in the Värpinge pilot!
During week 35, construction began on the first parts of the pilot in Värpinge, as part of the ISWIM project. This means we can now measure and monitor the flow of stormwater and the pollutants entering the stormwater facility.
We’re now installing the pilot!
Last week, construction began on the first components of the pilot in Värpinge, as part of the ISWIM project. This means we can now measure and monitor the flow of stormwater entering the stormwater facility.
The pilot plant at Testbed Ellinge handed over to VA SYD
During the spring and summer, we have been working on fine-tuning the pilot plant operation. On 15 July, the supplier Aquagreen handed over the plant to VA SYD.
Construction to Begin After Summer – ISWIM Takes the Next Step
Planning permission has now been granted! Construction of the pilot facility for the ISWIM project will begin after the summer – a key step towards the future of stormwater treatment.
New project! DT-N2O – Quantifying and minimising nitrous oxide emissions at wastewater treatment plants with digital twins
The project will build a digital twin, an automated process model, for the Käppala Wastewater Treatment Plant (WWTP) in Stockholm. The twin is used to quantify and minimise greenhouse gas emissions (mainly nitrous oxide).
Open position within Opti-SITE: Postdoctoral position in Water Resources Engineering at Lund University
Opti-SITE is an important part of the work to create climate-adapted and sustainable stormwater management in cities.
