Photocatalytic treatment of diverse contaminants of potential concern in oil sands process-affected water

Published: March 25, 2024

Oil sands process-affected water (OSPW), generated by surface mining in Canada’s oil sands, require treatment of environmentally persistent dissolved organic compounds before release to the watershed. Conventional chemical and mechanical treatments have not proved suitable for treating large quantities stored OSPW, biological recalcitrance some organics may be adequately addressed conventional passive systems. Previous work has evaluated photocatalytic as a advanced oxidation process (P-AOP) OSPW remediation. This expands upon this prior research further characterize effects chemistry on rate detoxification threshold. Under artificial sunlight, buoyant photocatalysts (BPCs) detoxified all samples within 1 week time with simultaneous polycyclic aromatic hydrocarbons, naphthenic acid fraction components (NAFCs), un-ionized ammonia. Overall, these results demonstrate photocatalysis an effective method contaminants potential concern (COPCs).
