Study
- Citation
- Saeed, T., Paul, B., Afrin, R., Al-Muyeed, A., & Sun, G. (2016). Floating constructed wetland for the treatment of polluted river water: A pilot scale study on seasonal variation and shock load. Chemical Engineering Journal.
- Study description
- This study tested a pilot scale floating wetland and reported the treatment efficiency of the wetland in removing contaminants from polluted river water. The study looked at removal of nitrogen and phosphorus as well as biogeochemical oxygen demand (BOD) and chemical oxygen demand (COD).
Response
- Cause term/trajectory
-
Plants (aquatic)
- Cause description
- Floating constructed treatment wetland with two macrophyte species (Phragmites australis and Canna indica)
- Effect term/trajectory
-
Water quality - nutrients (phosphorus)
(Decrease)
- Effect description
- Phosphorus was removed from water with the presence of the floating wetland species. Paper suggests phosphorus removal was through filtration-sedimentation processes. No test statistics were supplied.
