Description
The research works developed focus on investigating batch and/or fed-batch anaerobic bioreactors containing granular biomass (ASBR) or biomass immobilized on inert support (AnSBBR) applied to the treatment of domestic and industrial wastewater, with mechanical agitation or circulation of the liquid phase. The projects are related to process engineering and deal with the influence of process variables, such as agitation mode, bioparticle size, duration of the various process stages, and feeding strategy on the removal efficiency of carbonaceous organic matter, nitrogen and sulfur, as well as on the production of bioenergy in the form of hydrogen and methane. Possible need of supplemental substances is also assessed (buffering, micro and macronutrients). The approach favors critical topics related to kinetics, bioreactors and mass transfer in order to provide information for full-scale use of the investigated technological configurations.
