Dewatering oil sands tailings using EKS-DT will:
- Reduce the costs of tailings management,
- Reduce demand on fresh water sources by increasing the water available for reuse,
- Decrease the disturbed land footprint from tailings handling, storage, and disposal, and
- Reduce GHG and other air pollution emissions by rapidly consolidating the FFT eliminating fugitive emissions and by reducing the use of heavy equipment and other machinery.
EKS has prepared a detailed quantitative life cycle analysis for its technology and used these results to compare its economic and environmental performance with other dewatering technologies. The EKS-DT process clearly out performs existing technologies. These results provide compelling evidence of the ability of the EKS-DT process to make a significant contribution to the long-term sustainability of Alberta’s oil sands industry.
Similar benefits are available by applying EKS-DT to other mining operations and industries where difficult-to-dewater slurries and/or unstable clay soil conditions are present.
