Generación de bioelectricidad mediante celdas de combustible microbianas a partir de aguas residuales industriales textiles de Fashion Color, utilizando Chorella Vulgaris como biocatalizador en la Cámara Catódica, Pelileo 2015.

Abstract

In the present investigation was generated bioelectricity by microbial fuel cells (CCMs) from textile industrial waste water and activated sludge from Fashion Color Factory of Pelileo canton, using Chlorella vulgaris as biocatalyzer in the cathode chamber. The research is supported under the deductive method of research. Four simple camera CCMs, were implemented where CCMI, CCM2 and CCM3 (with biocatalyzer) and CCM4 (free the biocatalyzer control cell) with a total volume of 125 ml, the material used for the electrodes anode and cathode was carbon fiber, these electrodes were undergoing a pre-treatment to enhance the formation of biofilm and removal of impurities, used cellophane as proton exchange membrane the separation between the electrodes was 1 cm, the Anodic Chamber was fed with 120 mL of textile waste water which contained 10 mL of activated sludge, biofilm of microalgae Chlorella vulgaris was formed in the cathodic camera acting as biocatalyzer. The generated voltage was recorded in a NI DAQ 6009, for a period of 20 days of monitoring. The microbiological analysis determined the presence of units forming colonies (UFC) anaerobic, facultative anaerobic and aerobic microorganisms. Within the results in the generation of bioelectricity the CCM1. CCM2, CCM3 was 43%, 26% and 25% higher than the control cell. Through the chemical physical analysis determined that the concentration of heavy metals, Cr and Zn decreased significantly in the CCMs, the CCM4 reported one decrease greater than 98% Zn and 87.4% of Cr. In conclusion the CCMs with biocatalyzer recorded higher production of bioelectricity, the CCM4 reduces most heavy metals. The settings on a CCM's dual-camera is recommended to control the parameters that influence the performance of Chlorella vulgaris.
