Constructed Wetlands for Treating Acid Mine Drainage

has been abandoned by mining activities. Constructed wetlands have been considered a possible solution to the long-term remediation of acid mine drainage. Studies have revealed positive results regarding the use of creating wetlands to remediate a human induced pollutant (Fennessy

Use of constructed wetlands for acid mine drainage ...

Constructed wetlands have been used for over two decades for the treatment of acid mine drainage (AMD). Through a variety of physical, chemical, biological processes, these wetlands are effective in reducing acidity and removing up to 99% of iron and aluminium from AMD, but they only remove 20-30% of the manganese loading.

Abstract Constructed wetlands oer green and sustainable treatment, but how long will they really work? A wetland in northeastern Minnesota has been successfully treating mine drainage for almost 20 years. The primary removal processes include adsorption, ion exchange and com-plexation.

A Handbook of Constructed Wetlands - US EPA

Constructed wetlands are now used to improve the quality of point and nonpoint sources of water pollution, including stormwater runoff, domestic wastewater, agricultural wastewater, and coal mine drainage. Constructed wetlands are also being used to treat petroleum refinery wastes, compost and landfill leachates, fish

Constructed Wetlands coal Mine Drainage, Volume 4

For some mine drainages, constructed u-et- lands provide the treatment needed to produce water that meets effluent limitations. For other drainages, constructed wetlands are used to pretreat mine water before conventional treatment, thereby lowering treatment costs, or they are used as a part-time alternative to full-time treatment.

Acid Mine Drainage Treatment Using Constructed Wetland

constructed wetland. Acid mine drainage samples were collected from Mpumalanga (South Africa) and they were characterized for heavy metals and sulphate concentrations (with pH ranging between 2.6 and 2.7). Three constructed wetlands (all packed similarly) were built and employed to treat acid mine drainage samples with different metal ...

A field study of constructed wetlands for preventing and ...

01-05-2009  The formation of acid mine drainage (AMD) from mine tailings is a severe environmental problem associated with tailings impoundments. The study evaluated the ability of wetlands built on tailings impoundments to prevent AMD formation and to treat already formed AMD, with special emphasis on the role of wetland plants in the remediation process.

Review of Constructed Wetlands for Acid Mine Drainage ...

The problem of AMD concerns at active and abandoned mine sites. Acid mine drainage needs to be treated since it can contaminate surface water. Constructed wetlands (CW), a passive treatment technology, combines naturally-occurring biogeochemical, geochemical, and physical processes. This technology can be used for the long-term remediation of AMD.

WETLAND SIZING, DESIGN, AND TREATMENT

Constructed wetlands are a proven means of treating and improving the quality of mine drainage, but they do so with varying degrees of effectiveness. There are numerous reasons as to why constructed wetlands vary in treatment effectiveness, but one important consideration relates to the sizing of such systems. That is, how large does a wetland ...
