Of the 4 microbial cells, it resulted that cell 4 generated more energy with 0.8960 V, then cell 3 with 0.8410 V, cell C1 with 0.8240 V and finally cell C2 with 0. 4920 V; that is when using in the anionic cell Pseudomonas aeruginosa bacteria in sludge substrate with wastewater, with aluminum electrode and in the cathodic cell a graphene electrode in copper sulphate solution, proved to be the most optimal in obtaining energy; therefore, microbial fuel cells allows obtaining bioelectricity while in this process decreases organic pollutants with the presence of carbon and nitrogen (Sawasdee V. and Pisutpaisal N., 2018) that in high levels are found in sewage 0.8410 0.7510 0.0000 0.2000 0.4000 0.6000 0.8000 1.0000 6.9 7.1 7.3 7.5 7.7 7.9 8.1 8.3 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 V o lt ag e (v )p H Time (Days) pH Energy (C3) Energy (C. control 6) 0.8960 0.7570	cache/cet-12522.pdf	txt/cet-12522.txt
