Constructed Wetlands - Pollutant Removal Mechanisms (RV-7803)
Constructed wetlands can be used as an artificial wastewater treatment system. This 2-hour interactive online course covers the details of how suspended solids, organic matter, nitrogen, phosphorus, pathogens and other contaminants are separated and transformed in constructed wetlands. These processes are generally different between constructed wetlands and standard wastewater treatment systems. This course also includes a discussion on modeling performance of constructed wetlands and guidance on models that should be used. Additional RedVector.com courses are available on other topics related to constructed wetlands. This course is based on guidance documents published by the Environmental Protection Agency. There is a test and the end of each section of this course.

Upon completion of this course, you will:
Understand the mechanisms of separation and transformation of suspended solids in a constructed wetland and how the constructed wetland could potentially increase solids levels.
Know how organic matter is removed in a constructed wetland and how increases in dissolved organic matter could occur.
Have learned how nitrogen is removed in a constructed wetland and the seasons of the year when removal will be greatest.
Understand how phosphorus is removed in a constructed wetland and why effluent concentrations may be higher than influent concentrations during some seasons of the year.
Know how wetlands affect the fate of pathogens in the wastewater.
Have learned how trace metals and other contaminants are removed in a constructed wetland.
Recognize how removal mechanisms differ between free water surface wetlands and vegetated submerged beds.
Understand the basic concepts of modeling the effluent from a constructed wetland.
