Constructed aerobic wetlands (Fig. 1) are based on ,aeration, of the water to be treated, resulting in transformation of dissolved Fe to the solid phase via oxidation. Thus, aerobic wetland treatment is very effective in treating Iron-rich ,mine, waters, yet they commonly have limited capability to neutralize acidity.
