“…Research has indicated that domestic wastewater contains approximately 9.3 times more energy than what is required for its treatment in treatment plants (Heidrich et al, ). However, power generation from industrial wastewater has also received great attention in recent years in attempts to compensate for the high costs of the associated treatment processes (Kargi and Eker, ; Safwat et al, ). There is a critical need to develop suitable and reliable technology for wastewater treatment.…”

This work assessed the performance of a single-chamber microbial fuel cell (MFC) with various substrates. Primary settled domestic wastewaters were used to simulate wastewaters of high biodegradability; while phenol-based wastewaters and benzene-based wastewaters were used to simulate wastewaters of low biodegradability. Experiments were performed at initial pH values of 6, 7 and 8. The maximum voltage production, power density and removal of substrate were obtained using primary settled domestic wastewater, whereas the lowest values were obtained using phenol-based wastewater. The maximum chemical oxygen demand removal efficiency, phenol removal efficiency and benzene removal efficiency were 80.8, 63.3 and 77.8%, respectively. The performance of the MFC was enhanced by increasing the influent pH. The lowest coulombic efficiencies were obtained from phenol-based wastewater and benzene-based wastewater, which indicated that electrogenic bacteria were not the primary microorganisms responsible for the biodegradation of low biodegradable wastewater.

“…The more distant the electrodes are, the longer it takes for electrons to cross. Therefore, at more distant electrodes and for a fixed duration of EC, less electrons and consequently less hydroxide ions will be produced [22]. It can also be seen from Fe electrodes.…”

“…Numerous technologies have been investigated to eliminate phenol from wastewater, such as chemical oxidation, osmosis, ion exchange, electrochemical methods, membrane filtration, microbial fuel cells, precipitation, and coagulation [2,6,7]. However, these technologies have some issues, such as high cost, low efficiency, and toxic by-products [1,8].…”

The uptake of phenol using kaolin and fuller's earth and the comparison of their effects with bentonite are investigated in this study. In addition, X-ray fluorescent, X-ray diffraction, and thermogravimetric analyzes were carried out to examine the characteristics of the three adsorbents. Adsorption of phenol as a function of pH level was also investigated. The points of zero charge for kaolin, fuller's earth, and bentonite were determined to be 5.9, 8, and 7.7, respectively. To study the adsorption kinetics and mechanisms, various kinetic models were explored. Two-parameter and three-parameter isotherm models were employed for equilibrium studies. The results showed that decreasing the pH value led to an increase in phenol uptake. The maximum removal efficiencies were 34.35%, 23%, and 42.63% for kaolin, fuller's earth, and bentonite, respectively, for 0.5 g of adsorbent and pH = 4.5. Phenol uptake on the three adsorbents can be expressed by pseudo-second order kinetics. Whereas the Freundlich isotherm suits the experimental data for adsorption onto bentonite and fuller's earth, the Temkin isotherm well suits the experimental data for uptake onto kaolin. The Fourier transform infrared and scanning electron microscope were used in the analysis of the adsorbents surface prior to and after the process of adsorption.
