“…For example, Hsieh et al achieved 60% removal of dissolved organic carbon using vacuum membrane distillation, resulting in a final distillate concentration of 36.1 mg/L-DOC. 24 Similarly, Pawar et al reported 87% DOC removal with an air-gap membrane distillation system leading to a final distillate concentration of 8 mg/L-DOC. 25 Targeted and nontargeted analysis showed that none of the analyzed VOCs and SVOCs were detected after MBR treatment, with one exception, the diesel range organics (DRO, nC10 to nC28), shown in Figure 2, which remained in the PW throughout the entire treatment train.…”

“…Previous studies have shown higher removal rates of organic constituent from Permian Basin PW with MD; however, in those studies the feed concentration was much higher and the authors were unable to achieve the low concentration observed with the current study, which was 2.8 mg/L TOC. For example, Hsieh et al achieved 60% removal of dissolved organic carbon using vacuum membrane distillation, resulting in a final distillate concentration of 36.1 mg/L-DOC . Similarly, Pawar et al reported 87% DOC removal with an air-gap membrane distillation system leading to a final distillate concentration of 8 mg/L-DOC …”

Water scarcity and increased energy demands have put a strong focus on improving industries at the heart of the water−energy nexus. Treatment of oil and gas produced water (PW) can help reduce freshwater consumption during hydraulic fracturing, especially in arid regions, while also removing harmful contaminants from entering the environment. However, it is also difficult to treat because PW contains high concentrations of many environmentally toxic contaminants, which require complex and expensive treatment processes to achieve their removal. To demonstrate the possibility of PW treatment and reuse in the O&G industry, a comprehensive environmental toxicity and water quality analysis throughout a five-process treatment train was performed on high salinity (>120 g/L) Permian basin raw PW. The concentrations of naturally occurring radioactive materials were reduced by over 99%, total organic carbon was reduced by 93%, and inorganic constituents, including total dissolved solids, were reduced by over 99%. Compounds that induced the aryl hydrocarbon receptor and caused cytotoxicity in MCF-7 cells were also removed. Overall, the results of this study show that a short treatment train (five distinct unit processes) can be effective in treating PW to a level suitable for use outside of the oil industry.
