An Evaluation of Sugarcane Bagasse as a Feedstock in a Biological Treatment System for Mine Affected Waters

摘要

A passive biological treatment system for sulfate-rich Acid Rock Drainage has been investigated, focussing on using waste biomass such as grass cuttings and sugarcane bagasse to raise the water pH and supply organic carbon as a food source for bioremediation of sulfate by Sulfate Reducing Bacteria. The objectives of this study are to assess the pH change and soluble organics released on contact between sugarcane bagasse and ARD, and if the model treatment process can run only on waste biomass.
