“…The bacteria used in MFC can convert the stored chemical energy in the bonds of organic matter directly into renewable energy [5]. In few studies, phenol or glucose-phenol mixture has been used as substrates in MFC to investigate the degradation of phenol and simultaneous electricity generation [6,7]. The co-substrate glucose was used to reduce the toxic effect of phenol on bacterial metabolism during shock load or temperature changes.…”

Microbial desalination cell (MDC) has great potential toward direct electricity generation from wastewater and concurrent desalination through potential difference developed due to microbial activity. Degradation of phenol by isolate Pseudomonas aeruginosa in anodic chamber and simultaneous desalination of water in middle desalination chamber of multichamber MDC is demonstrated in this study. Performance of the MDCs with different anodic inoculum conditions, namely pure culture of P. aeruginosa (MDC-1), 50 % v/v mixture of P. aeruginosa and anaerobic mixed consortia (MDC-2) and anaerobic mixed consortia (MDC-3), was evaluated to compare the phenol degradation in anodic chamber, bioelectricity generation, and simultaneous total dissolved solids (TDS) removal from saline water in desalination chamber. Synergistic effect between P. aeruginosa and mixed anaerobic consortia as inoculum was evident in MDC-2 demonstrating phenol degradation of 90 %, TDS removal of 75 % in 72 h of reaction time along with higher power generation of 27.5 mW/m(2) as compared to MDC-1 (95 %, 64 %, 12.8 mW/m(2), respectively) and MDC-3 (58 %, 52 %, 4.8 mW/m(2), respectively). The results illustrate that the multichamber MDC-2 is effective for simultaneous removal of phenol and dissolved solids contained in industrial wastewaters.

“…The long-term exposure of phenol and its derivative compounds to animal results in changes of the lung, liver, skin, and kidney (Bruce et al 1987). Most treatment methods for removal of phenol are physiochemical (e.g., adsorption and chemical oxidation) and biological process (e.g., activated sludge and anaerobic digestion).…”

“…Biological treatment is widely used in phenol treatment because it is a simple and effective method (Garcia-Morales et al 2015;Duan 2011). Recently, bioelectrochemical method has been extensively used in aerobic/anaerobic treatment of wastewater (Firman et al 2013;Tartakovsky et al 2011).…”

The effect of direct current (DC) on phenol biodegradation under aerobic/anaerobic condition was investigated in this study using a bioelectrochemical reactor. It was found that phenol biodegradation was inhibited with current ranged from 10 to 40 mA. The growth of biomass was reduced to 43.2 ± 6.6 % for aerobic sludge and 38.6 ± 7.3 % for anaerobic sludge, but the loosely bound extracellular polymer substances (LB-EPS) were increased 91.2 ± 1.3 % for aerobic sludge and 62.8 ± 0.8 % for anaerobic sludge as the current increased from 10 to 40 mA. Adenosine triphosphate (ATP) content of aerobic sludge was also reduced 0.481 ± 0.04-fold and 0.512 ± 0.05-fold lower and 1.34 ± 0.13-fold higher than that of the control when the current was increased from 10 to 40 mA. The results of phosphate buffer saline adding treatment indicated that lower pH caused by a DC above 10 mA was responsible for the reduced phenol biodegradation, leading to the reduction of biomass. However, lower intensity of current (5 mA) had no significant impact on phenol degradation rate, pH, LB-EPS, ATP content, and cell growth of aerobic/anaerobic sludge. These results give us a more detailed understanding of the effects of electricity on the treatment of phenol containing wastewater.

“…Biodegradation is another method that can be used for treatment of wastewater containing phenol (Piubeli et al, 2012;Friman et al, 2013;Kalaiarasan and Palvannan, 2014;Zidkova et al, 2013). Nevertheless, the presence of phenols reduces the biodegradation of other compounds when phenol concentration exceeds 400 mg LG 1 (Viero et al, 2008).…”

Abstract:In this study, removal of phenol which is classified as priority pollutant by US EPA, was experimentally investigated using different removal techniques including; adsorption using Granular Activated Carbon (GAC), biodegradation using six different active phenol uptaking bacteria, combined GAC sorption and biodegradation (Biological Activated Carbon, BAC) and GAC coupled with inactive bacteria (biosorption). A solution of 100 mg LG 1 phenol at room temperature was considered as the wastewater. The study was performed in the temperature range 25-30°C. The results of these different techniques revealed that activated carbon sorption is better than the other methods in removing phenol. The removal efficiency of this technique reached a value of 97% corresponding to residual phenol concentration of 3 mg LG 1 . The equilibrium sorption was reached after 48 h of contact. The adsorption data was better fitted to Langmuir model with adsorption capacity of 90 mg gG 1 . The adsorption was found to be second order with both intraparticle diffusion and film diffusion to control the adsorption process. The least effective removing method of phenol was the biodegradation using active bacteria alone. The residual concentration of phenol attained by this method was 17 mg LG 1 . According to the results of this study approximately 80% of the overall biological activity for removal of phenol was due to the surface sorption on the cell wall, whereas, about 20% of this activity was due to biodegradation.
