CONSTRUCTED WETLAND TREATMENT SYSTEMS – PUTTING WETLAND BIOGEOCHEMISTRY TO WORK
Wetlands are aquatic systems that host unique biogeochemical reactions used in constructed wetland treatment systems (CWTSs) to treat (transfer and transform) elements and compounds in industrial waters to mitigate risks. This presentation includes two case studies to illustrate process-based design of CWTSs. The A-01 CWTS at the Department of Energy’s Savannah River Site was designed to treat metals (e.g. copper, zinc, and mercury) in stormwater runoff and industrial process water. Operating for more than 15 years, this CWTS has and continues to perform as designed. In another study, wetlands were designed to treat large volumes of oil sands process-affected water (OSPW) from the Athabasca oil sands near Ft. McMurray (Alberta, Canada). A hybrid pilot-scale CWTS was designed to promote treatment processes for metals (e.g. Al, Cu, Ni, and Zn) and naphthenic acids (NAs) using sequential reducing and oxidizing wetland reactors and a solar photocatalytic reactor using fixed-film titanium dioxide. Results from this study provide proof-of-concept data to inform hybrid passive or semi-passive treatment approaches (i.e. constructed wetlands) that will be used to mitigate targeted constituents in OSPWs.
