Abstract

The development of new technologies to meet energy demand andwastewater treatment is becoming increasingly relevant. In view of this, theMicrobial fuel cell (CCM) emerges as an alternative to conversionorganic matter into electric energy from water treatmentResidential However, the power generation to be obtained in CCMs still presentsscientific challenges for better technology. So the presentstudy seeks to better understand these challenges to improve and optimize generationof electricity in bioelectrochemical reactors. The study will be carried out with a prototypebench-scale tubular MCC study developed in our research group,applied to synthetic effluent treatment simulating high-load wastewaterOrganic. Four CCMs (R1, R2, R3 and R4) will be operated under continuous flow, wherewill be studied in 3 different conditions / phasesunits R1 and R2 at room temperature,R3 and R4 at 55º C. In phase 2 R3 and R4 will be submitted to a flow rate of 516 mL.d withpurpose of evaluating the influence on coumlombian efficiency and CCM potential. Atphase 3 the four reactors will be operated with effluent at 10 gDQO.L-1 having theiroperation characteristics maintained. The evaluation of the treatment efficiency ofeffluent will be evaluated by analysis of physicochemical parameters. Samples ofbiofilm adhered to the anode and cathode will be collected at the end of the third phase, whereDNA extraction and subsequent sequencing will be performed. So it is expected to getresults that contribute to system scaling and increased efficiencyin the treatment of wastewater with the consequent generation of bioelectricity
