Study
- Citation
- Tanner, C. C., & Headley, T. R. (2011). Components of floating emergent macrophyte treatment wetlands influencing removal of stormwater pollutants. Ecological Engineering.
- Study description
- This study looked at the influence of different components of floating treatment wetlands (FTWs) on pollutant removal from stormwater. The study used a series of mesocosm tanks to test removal rates under several treatments made up of different aspects of FTWs.
Response
- Cause term/trajectory
-
Plants (aquatic)
- Cause description
- Floating treatment wetlands
- Effect term/trajectory
-
Water quality - nutrients (phosphorus)
(Decrease)
- Effect description
- Reduction of dissolved reactive phosphorus (DRP) from water. The presence of planted floating mats (in the presence of fine suspended solids) significantly improved removal of phosphorus from the synthetic stormwater. Removal rates ranged from 30% to 60% of DRP and 58% TP after 7 days for planted treatments.
