The current work removed the organic material from an artificial cacao washing effluent using microbial fuel cells coupled with an upflow fixed bed anaerobic reactor and a heterogeneous photocatalyst.  Also, the  the microbial charge was reduced, avoiding the proliferation of pathogenic micro organisms which interfere with the increase in the biochemical demand for oxygen, biological alteration and the reduction of quality in the bodies of water; at the same time, the generation of energy in volts and amps produced in the RAFA (acronym in Spanish) was measured.  For this, the residual water at the entrance, during the process and at the exit was characterized.  At the entrance and exit, the DBO5, total dissolved solids, reduction potential, conductivity, pH, temperature and %NaCl were measured; during the process the pH, amperage and voltage were measured.  A rem...
