“…Double-chamber MFC is the most investigated model of MFC reactor, in which the electrode chambers are separated by proton exchange membranes (Ali, Gomaa, Fathey, Abd, & Kareem, 2015;Baranitharan et al, 2015;Greenman, Gálvez, Giusti, & Ieropoulos, 2009;Larrosaguerrero et al, 2010;Li, Zhang, Lin, Han, & Lei, 2010;Sun, Li, Li, Hu, & Zhang, 2013). However, this model has its limitation to a full-scale plant application, due to the high cost of membranes used and high possibility of clogging thus inhibiting the hydrogen transfer.…”

Microbial fuel cell (MFC) is a new proposed technology reported to generate renewable energy while simultaneously treating wastewater. Membraneless microbial fuel cell (ML-MFC) system was developed to eliminate the requirement of membrane which is expensive and prone to clogging while enhancing electricity generation and wastewater treatment efficiency. For this purpose, a reactor was designed in two chambers and connected via three pipes (1 cm in diameter) to enhance fluid diffusion. Influent flowrate was maintained by adjusting peristaltic pump at the base of anaerobic chamber. Carbon cloth (235 cm2) was used as anode and paired with gas diffusion layer (GDL) carbon-Pt as cathode. Anaerobic sludge was filtered and used as starter feed for the anaerobic chamber. The experiment was carried out by feeding synthetic wastewater to anaerobic chamber; while current response and potential were recorded. Performance of reactor was evaluated in terms of chemical oxygen demand (COD). Electroactive microbe was inoculated from anaerobic sludge and showed current response (0.55-0.65 mA) at 0,35 V, range of diameter 1.5-2 µm. The result of microscopics can showed three different species. The microbial performance was increased by adding ferric oxide 1 mM addition as acceptor electron. The reactor was able to generate current, voltage, and electricity power of 0.36 mA, 110 mV, and 40 mWatt (1.5 Watt/m2), respectively, while reaching COD removal and maximum coulomb efficiency (EC) of 16% and 10.18%, respectively.

“…Eficiências de remoção menores que os obtidos no presente estudo foram obtidas por Ali et al (2015) com águas residuárias domésticas e uma DQO de 350 mg.L -1 conseguiram uma remoção de DQO de 71,8 % e 72,85 % mesmo com correntes elétricas maiores do que o presente trabalho (0,784 mA e 0,645 mA). Muthukumar e Sangeetha (2014) utilizaram uma CCM de duas câmaras com uma MTP de ponte salina, capacidade de 1,8 L em batelada com eletrodo de folhas de grafite não revestidos de 0,027 m 2 para cada câmara, inoculada com 10 g.L -1 de lama de processamento de sago (um amido de palmeira) e operada com águas Não foi observado relação entre de remoção de DQO e geração de energia elétrica.…”

Neste estudo foi investigada a possibilidade de geração de eletricidade a partir do soro de queijo diluído em uma célula combustível microbiana (CCM) de duas câmeras sem mediadores. A CCM 1 foram inoculadas com lodo anaeróbio de lagoa de estabilização usada no tratamento de efluentes de abatedouro de aves e CCM 2 inoculada com sedimento de um rio. As CCM foram operadas por 21 dias em temperatura ambiente e foram monitoradas quanto à geração de corrente elétrica. Durante a operação das CCM 1 e CCM 2 a corrente elétrica máxima foi de 0,285 mA e 0,256 mA, a densidade de potência de 0,60 mW.m-2 e 0,50 mW.m-2 e remoção de DQO de 88% e 85%, respectivamente.

Microbial fuel cell (MFC) is a technology that is not only able to produce energy but also treats wastewater. The membraneless microbial fuel cell (ML-MFC) system was developed to avoid the use of membranes that are prone to clogging and are less applicable. The reactor was made and arranged in two chambers connected by pipes and the fluid flow rate is set using a peristaltic pump. Three anodes (carbon cloth) were paired with a carbon-Pt cathode GDL (Gas Diffusion Layer) type. The reactor was applied to wastewater taken from the industrial WWTP unit at the point before and after UASB. ML-MFC reactors can produce currents of 0.2 mA (before UASB) and 0.25 mA (after UASB). Current production is strongly influenced by the flow rate and characteristics of wastewater. Increased flow rates and complex character of wastewater will reduce current production. The electric power produced is 0.035 mwatt for wastewater before UASB and 0.086 mwatt after UASB with a COD removal is close to the same, which is 21% at a flow rate of 11 L / min1
