This study describes a new method, to treat acid mine wastewater, containing high amounts of heavy metals and sulfate by biotechnology., Sulfate reducing Bacteria, (SRB) was inoculated in an up-flow multiple bed bioreactor treating practical wastewater. In addition to precipitation processes, water purification was also possible with the metabolism process of microorganisms. Iron dust was added to the system to enhance the activity of SRB and ensure the, treatment, …

Over the past three years, Noranda Technology Centre (NTC) has evaluated the feasibility of using sulphate-reducing bacteria (SRB) to treat acid mine drainage (AMO), in a pit or an underground mine. Following an initial study conducted in batch flasks that determined major process parameters (residence time, temperature effect, nutrients and substrate requirements), a conceptual flow sheet was developed.
