Current status on Microbial Fuel Cell (MFC) technology

2022-01-01 , Huzairy Hassan , Raudzah Mohd Zahir , Ahmad M.A. , Mismisuraya Meor Ahmad

Agricultural and industrial activities in Malaysia have adversely impacted environmental quality leading local researchers to mobilize their expertise and resources to protect the environment from this alarming situation. The palm oil industry, for instance, generates an abundance of wastes (such as palm oil mill effluent [POME]), which calls for effective technological tools to reduce these recalcitrant wastes from spreading further. Microbial fuel cell (MFC) is an emerging technology for wastewater treatment and electricity generation simultaneously, which appears to be the most advantageous solution for these environmental concerns. This chapter reviews the prospects of MFC research with a special emphasis on the current MFC status in Malaysia. It begins with an overview of MFC principles, electron transfer mechanisms, and bio-electrochemical performance. Following that, a review of the recent MFC developments and activities by Malaysian researchers is discussed with an emphasis on POME utilization. This chapter concludes with several resolutions to the main challenges researchers and scientists are facing regarding the scalability of MFC for electricity recovery and wastewater treatment.

Carbonized chilli stalk adsorbent to remove methylene blue dye from aqueous solution: Equilibrium and kinetics studies

2021-05-24 , Aziz A. , Huzairy Hassan , Yahaya N.K.E.M. , Karim J. , Ahmad M.A. , Karim K.A.

The fast growth of textile industry has led to afflictive water pollution problems. The discharge of dyes into the environment poses health threats to the ecosystem due to their carcinogenicity and mutagenicity. Adsorption process is among the most utilized approach in treating textile wastewater. Chilli stalk which is abundantly available as agrowaste was transformed into adsorbent through carbonization process at various temperatures for the adsorption of methylene blue (MB). Dye batch adsorption studies were conducted to evaluate the effects of initial dye concentration (25 – 300 mg/L), contact time (0 – 24 hours) and carbonization temperature (350 - 400 °C). The surface characteristics, proximate and elemental analyses, surface morphology and chemistry were studied on both chilli stalk (CS) and carbonized chilli stalk adsorbent (CCSA). The maximum MB dye removal was 97.04% at 400 °C of carbonization temperature. The data fitted Freundlich isotherm model and pseudo-second-order kinetic model for adsorption equilibrium and kinetic studies, respectively.

Application of OPEFB fibre based electrode in microbial fuel cell system for electricity generation and chlorophenol degradation

2021-05-24 , Raudzah Mohd Zahir , Huzairy Hassan , Ahmad Anas Nagoor Gunny

Microbial fuel cell (MFC) has emerged as one of the potential technologies for sustainable bioelectrical energy recovery and reduction of recalcitrant wastes. The MFC performance is greatly influenced by the anode materials which serve as the support for exoelectrogenic bacteria attachment. In this study, oil palm empty fruit bunch (OPEFB) is proposed as an alternative anode material prepared via a direct carbonization process using tube furnace owing to its good conductivity property. The carbonization process was conducted under nitrogen gas flow at 900℃ with a constant heating rate of 5℃/min. The anode was prepared by mixing the carbonized OPEFB with polytetrafluoroethylene (PTFE) binder. When used in MFC, the OPEFB-anode generated a maximum current density of 97.30 mA/m2, which is comparatively higher than that of the conventional carbon cloth anode (76.24 mA/m2). Our MFC system had also resulted considerable chemical oxygen demand (COD) and 2-chlorophenol reductions of 77% and 75%, respectively. This study could support future research on freely-available OPEFB materials for high performance MFC anode.

Preliminary comparison of 2-chlorophenol biodegradation using microbial fuel cell and anaerobic systems

2022-04-20 , Raudzah Mohd Zahir , Huzairy Hassan , Ahmad M.A.

2-chlorophenol (2CP) is a typical contaminant found in industrial effluent that is both hazardous and persistent in the environment. The bioelectrochemical degradation of 2CP has been approved as a preferred method for removing the abrasive 2CP from wastewater. In this work, a microbial fuel cell (MFC) system inoculated with palm oil mill effluent (POME) sludge was used to degrade 2CP. The changes of morphology of the anode biofilm were observed under a light microscope and scanning electron microscope (SEM) for 2CP-fed MFC compared with the biofilm inoculated in an anaerobic chamber (AC). Maximum current density generated by the MFC was 97.30 mA/m2 while degrading 75% 2CP. Lower 2CP degradation of 60% was observed using the AC. Also, the abundance of negatively stained bacteria is reduced in the AC biofilm. This research shows that bioelectrochemical 2CP degradation is more efficient than conventional AC degradation. POME has the potential to be a high-value substrate for bacteria that can generate electricity in the MFC while also degrading harmful 2CP.
