The biogeochemistry ,of acid mine, drainage (AMD) derived from waste rock associated sulphide mineral oxidation is relatively well characterized and linked to Acidithiobacillus spp.. However, little is understood about the microbial communities and sulphur cycling before AMD develops, key component on its prevention.

Constructed Wetlands for Wastewater Treatment
Constructed Wetlands for Wastewater Treatment

Free Water Surface Constructed Wetlands. A typical FWS CW with emergent macrophytes is a shallow sealed basin or sequence of basins, containing 20–30 cm of rooting soil, with a water depth of 20–40 cm. Dense emergent vegetation covers a significant fraction of the surface, usually more than 50% ( Figure 2 ).
