Apr 14, 2021 Canada's oil sands industry is one of the largest suppliers of world energy whose sustainable expansion depends strongly on the treatment and reuse of the produced water during resource extraction 1
Syncrude Canada Limited’s Fort McMurray oil sands mining operations has been operating under the concept of zero discharge and total containment of wastewaters since start up in 1978. During this period a considerable volume of contaminated water has been assimulated in a large on-site tailings pond at a substantial costs to the company
Jun 23, 2021 Technologies such as bio adsorption are being applied as low cost technology for gold wastewater processing. This paper reviews the potential to treat gold wastewater using bio adsorbents. The efficiency of the wastewater treatment is dependent on the quality of wastewater, the characteristics of the bio adsorbent used and the process conditions

Apr 01, 2014 More detailed technology evaluations are publically available via the Oil Sands Tailings Technology Deployment Roadmap (Consortium of Tailings Management Consultants, 2012). However, substantial performance variations do exist from case to case, which reflect the inadequacy of our current understandings and highlight several key knowledge gaps
The applicability of the technology in produced water treatment is qualitatively scored from poor to excellent. The ranking is based on: Poor - the technology can not be used to treat CBM produced water Moderate - there are significant hurdles, but under certain circumstances the technology may be appropriate for treatment of CBM produced water
