TY - THES TI - Construcción de un biofiltro para la remoción biológica de sulfuro de hidrógeno en aire utilizando residuos de Moringa oleífera AU - Mora Toloza, Brisley Yuliana AB - Hydrogen sulfide (H2S) is a colorless, flammable, toxic gas with a characteristic "rotten egg" odor, produced by the activation and reduction of sulfate to sulfides. Currently, there are several chemical and biological methodologies, used for the elimination of this compound. However, the chemical or physical strategies typically transform the contaminant to a more toxic compounds and have a low removal efficiency. This is why there is a need of optimizing the biological technologies optimized for the treatment or elimination of H2S. Therefore, the objective of the present study was to develop an airlift biphasic biofilter using Moringa oleifera residues as an immobilizing material, under different retention times and contaminant concentrations. The biofilter was efficient to remove H2S in contaminated air. The biofilter removal efficiency was not affected by the inlet H2S concentrations; however, a direct relation was found between the retention time and gas removal with significant differences between 0 and 15 minutes as well as 0 and 30 minutes, but not between 15 and 30 minutes retention. In conclusion, it was possible to build an efficient biofilter for the removal of H2S in air. The residues of Moringa oleifera husks have shown on their own a retention and adsorption effect on the H2S present in the contaminated air; likewise, the biofilter built with Moringa oleifera residues was efficient to eliminate up to 65% of the H2S present in polluted air currents.
