摘要: Unconventional oil and gas exploration generates an enormous quantity of wastewater, commonly referred to as flowback produced water (FPW). Limited freshwater resources stringent disposal regulations have provided impetus for FPW reuse. Organic inorganic compounds released from the shale/brine formation, microbial activity, residual chemicals added during hydraulic fracturing bestow a unique well temporally varying chemical composition this wastewater. Studies indicate that many found in are amenable biological degradation, indicating treatment may be viable option processing This review discusses characterized contaminants current knowledge on their biodegradability, including enzymes organisms involved. Further, perspective recent novel hybrid treatments application gained omics studies improving these is explored.
