Research groups from São Carlos School of Engineering of University of São Paulo (EESC/USP) and Mauá School of Engineering of Mauá Institute of Technology (EEM/IMT), in partnership and with support of FAPESP, have been studying anaerobic reactors operated in sequential batches with the goal of improving the performance and feasibility of their application since 1998. Currently the research projects are directed to bioenergy production, both hydrogen as methane, and to the environmental suitability of the treated effluent. Such projects are linked to the thematic project entitled "Bioenergy Production in Wastewater Treatment and Environmental Suitability of Effluents and Waste Generated" (FAPESP N°. 09/15.984-0). This research aims to evaluate the anaerobic reactor operated in batch and fed batch mode, containing immobilized biomass on inert support and recirculation of the liquid phase applied to biohydrogen production from co-digestion of glycerin (biodiesel production effluent) and whey (dairy production effluent). The stability, performance and conversion factor (between generated biogas and consumed organic matter) will be analyzed in terms of the percentage of each substrate fed to the system, the organic load variation (imposed by modifying the reactor influent concentration and cycle time), the filling time and temperature (15, 30 and 45 °C). The assays shall be performed using different proportions of the aforementioned substrates with different volumetric organic loading rates (10.3, 17.1 and 24.0 gDQO/L.d), which are modified depending on: (I) the influent concentration (3000, 5000 and 7000 mgDQO/L) and (II) the cycle time (4, 3 and 2 hours, or 6, 8 and 12 day cycles). Low density polyethylene will be used as inert support for biomass immobilization and poultry slaughterhouse sludge with thermal pretreatment will be used as inoculum. Assays for the production of biomethane will also be conducted from the co-digestion proposed in this project (with AVOL of 6.4 gDQO/L.d). (AU)
