Mashreki Sami was one of the speakers in the conference and presented his study on how microplastics in greywater can be removed with a green wall, i.e. a vertical configuration of plants with different filter materials that are loaded with greywater.
Rasmus Klapp presented his ongoing research on how a reedbed wetland system can treat raw wastewater in cold climate, and how well it treats microplastics.
Representing Stormwater&Sewers, Inga Herrmann also participated in the four-days conference that was beautifully situated in central Lyon. Yet, one of the days was reserved for technical tours to various wetland treatment systems in the area.
