“…Microbial Capacitive Desalination Cell (MCDC), like MDC, has three chambers but the middle chamber contains electrodes for Capacitive Deionization. These electrodes have a large surface area that adsorbs organic and inorganic ions under applied electrical potential (Forrestal et al, 2015;Monzon et al, 2017;Shrestha et al, 2018). On the other hand, Microbial Electrochemical Cell (MEC) requires external electricity to perform electrolysis with the aid of microbes and can generate hydrogen as a byproduct (Ghasemi Naraghi et al, 2015).…”

Emerging Trends in Biological Treatment of Wastewater From Unconventional Oil and Gas Extraction

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

“…The studies reviewed had different configurations (Table 7). In two studies microbial fuel cells (MFC) were studied that consist of anaerobic treatment with biofilm-coated anodes and cathodes that form a cell contained within the reactor (Sheikhyousefi et al 2017;Shrestha et al 2018). As described by Sheikhyousefi et al (2017), the anodes and cathodes are constructed of treated carbon cloth.…”

“…As described by Sheikhyousefi et al (2017), the anodes and cathodes are constructed of treated carbon cloth. Microbial capacitive desalination cells (MCDC) were also studied where the anode and cathode are placed in separate compartments and a desalination compartment resides between the anode and cathode compartments (Forrestal et al 2015;Shrestha et al 2018;Stoll et al 2015). As described by Forrestal et al (2015), the desalination compartment consists of a series of nickel/copper electron collectors that have activated carbon cloth on either side and are separated from other collectors by plastic mesh.…”

“…The COD removal in the BES studies was consistently higher than 70%. In a study comparing MFC with MCDC, Shrestha et al (2018) found that the MFC yielded higher COD removal rates (85-96%) than MCDC (71-85%). Conversely, TDS was better removed in MCDC (65-74%) than in MFC (20-40%) (Shrestha et al 2018).…”

Biological treatment is effective but infrequently used for oil and gas produced water. To date, physical-chemical treatment methods have been favored due to the smaller space requirements and operational simplicity. Changing regulatory requirements and increased interest in recycling and beneficial reuse have led to increased interest in biological treatment. To elucidate its potential role, we reviewed and summarized 59 studies on the biological treatment of produced water. Oilfield produced water was predominantly studied (> 50%). More studies using real produced water were from China than from any other country (37%). Real produced water was used in most studies (73%). Studies were predominantly bench-scale experiments (69%). Fixed-film reactors were most prevalent (27%). Water quality of produced waters treated was variable; median total dissolved solids (TDS) was 28,000 mg L −1 and median chemical oxygen demand (COD) was 1125 mg L −1. Inhibition by salinity was variable according to the treatment system and study design, but efficacy generally decreased when TDS was above 50,000 mg L −1. For studies treating real samples, average COD removal was 73% when TDS was less than 50,000 mg L −1 , and 54% when TDS was greater than 50,000 mg L −1. Key issues were microbial acclimation, toxicity, biological fouling, and mineral scaling. Finding an inoculum was not problematic as microorganisms capable of degrading hydrocarbons were isolated from various environments. Treatment performance was better where synthetic produced water was used in lieu of real samples. Biological treatment is promising for producing effluents suitable for reuse, particularly where it functions as part of a larger treatment train.
