Food‐Processing Wastes

Abstract

Beverages and Fermentation A good deal of research in 2003 focused on optimization of existing wastewater treatment processes for winery, brewery, and distillery wastewater. Malandra et al. (2003) examined the microbiology of biofilms present on rotating biological contactor (RBC) discs treating winery wastewater. It was determined that the microbiological populations, consisting of several bacterial and yeast species, shifted over the duration of the evaluation period and that one particular yeast species was able to achieve high levels of COD reduction in synthetic wastewater. Garcia-Morales et al. (2003) studied the activity of biofilm in a thermophilic anaerobic fluidized bed reactor treating wine distillery wastewater. As a result of these studies, the authors were able to develop activity tests that could be used to determine, among other things, maximum methanogenic activities for various biomass carriers. Tests were also used to evaluate physical phenomena and parameters affecting treatment. Javier Benitez et al. (2003) studied the kinetics of chemical oxygen demand (COD) removal from wine distillery wastewater using both ozonation and aerobic biodegradation. Kinetic parameters were presented for both technologies for both continuous and discontinuous processes. Three different upflow anaerobic sludge blanket (UASB) reactors were
