Constructed Wetlands for Pollution Control

Course Overview

This online course evaluates the use of constructed wetlands (CW) in the treatment of municipal and industrial wastewaters, partially-treated effluents, run-off water and sludges. Following a review of the relevant legislative and regulatory framework associated with the discharge of treated effluents, it considers the typical design criteria used for horizontal flow, vertical flow and other forms of constructed wetlands, together with their construction and commissioning, whether as new build or retro-fit.

A series of case studies are used to explore the operation, performance, treatment efficiency and ultimate renewal/replacement procedure of a variety of CWs operating under different conditions, with different types of influent, in different locations. The module evaluates the applicability, benefits and limitations of CWs as a treatment technology together with the impact on carbon footprint when using this sustainable wastewater and sludge treatment technology.

  • Be able to describe the difference between natural wetlands and constructed wetlands for pollution control
  • Have a comprehensive understanding of where constructed wetlands can be used for pollution control
  • Understand the characteristics of wastewater and sewage
  • Have a basic knowledge of measuring flows through constructed wetlands.
