ISWIM’s Testbed Takes Shape, Constructed Wetland in Place
In western Lund, the research project ISWIM is building a testbed for innovative stormwater treatment solutions. The first stage consists of a constructed wetland, which is now complete.
Stormwater from one of the city’s most polluted areas flows into the wetland in western Lund, contributing high levels of contaminants to the Höje River.
A Two-Stage Process
In the first stage, the treatment performance of the wetland is measured and compared with that of biofilters and membranes. Here, particulate pollutants such as metals, nutrients and organic compounds are removed. The second stage involves activated carbon, which is intended to remove contaminants, including PFAS.
The goal is to develop an adaptable “toolbox” of treatment techniques that can be tailored to meet different needs and locations across the country and within the water and wastewater system. This is expected to benefit the entire Swedish water and wastewater sector. Therefore, it is important that the project brings together universities and water and wastewater companies from various parts of the country—from south to north.
