Escherichia coli removal in copper-zeolite-integrated stormwater biofilters: Effect of vegetation, operational time, intermittent drying weather

Highlights
- The first study investigating new biofilter designs with copper-zeolite.
- Consistently higher E. coli removal by new designs during 8 months monitoring.
- Improved E. coli removal by new designs after extensive drying weather.
- Survival of vegetation in new designs.
