Oil field fracking operations creates by-product “produced water” that is highly variable in composition and difficult to treat. This study aims to examine two novel treatment processes together in improving the quality of a synthetic, hypersaline produced water, and examines if effluent would be suitable for reuse. Here, we examine the ability of ferrate (VI) to coagulate organic and inorganic compounds to reduce turbidity while the efficacy of diisopropylamine (DIPA) in water extraction from the subsequent hypersaline solutions was also assessed under a variety of temperature ranges. For the final product water that is separated and treated through both processes, various characteristics were examined. Of note, significant reductions in turbidity (95.07% - 97.66% removal) and salinity (94.2% - 99.13% rejection) were observed at a variety of hypersaline concentrations and temperature ranges. Results indicate that this treatment process may show a favorable per-unit treatment cost compared to conventional processes.
