Constructed Wetlands for Treating Acid Mine Drainage
Constructed Wetlands for Treating Acid Mine Drainage

The design of a constructed wetland for the treatment of acid mine drainage varies upon site characteristics. According to Fennessy and Mitsch (1989), the most important design considerations are: biochemical processes, loading rate and retention time, slope, substrate, vegetation, sediment control, morphometry, seasonality, and regulatory issues.
