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.
