This paper explores the use of engineered biochar coupled with zero-valent iron (Fe0) and peroxymonosulfate (PMS) for the degradation of naphthenic acids (NAs) and fluorophore organic compounds (FOCs) in real oil sands process water (OSPW). Immobilizing Fe0 on biochar, a stable, porous carbon-based material, enhanced catalyst stability and degradation efficiency. Experimental results demonstrated significant removal of FOCs, classical, and oxidized NAs. Notably, 1 g/L of catalyst achieved ∼80 % removal of O2-NAs within 120 min, primarily through the generation of sulfate and hydroxyl radicals. To assess the toxicity of treated OSPW, cell-based immunotoxicity assays were conducted by measuring pro-inflammatory cytokine secretion in human and mouse macrophage cells. Treated OSPW exhibited a significant reduction in cytokine secretion, indicating lower immunotoxicity. Additionally, bacterial toxicity tests using Staphylococcus warneri revealed a reduced inhibitory effect on bacterial growth post-treatment. A comprehensive economic assessment benchmarked this method against various advanced oxidation processes (AOPs), demonstrating its cost-effectiveness, particularly when compared to light-based AOPs. These findings highlight Fe0-biochar-PMS treatment as a sustainable and efficient approach for mitigating OSPW toxicity, offering a viable solution for improved wastewater management in oil sands operations.T10-P04 University of Alberta | Publication | 2025-05-05 | |
