ABACO: A New Model of Microalgae-Bacteria Consortia for Biological Treatment of Wastewaters

Microalgae-bacteria consortia have been proposed as alternatives to conventional biological processes treat different types of wastewaters, including animal slurry. In this work, a microalgae-bacteria (ABACO) model for wastewater treatment is proposed, it being calibrated and validated using pig The includes the most relevant features microalgae, such light dependence, endogenous respiration, growth nutrient consumption function availability (especially inorganic carbon), in addition already reported heterotrophic nitrifying bacteria. interrelation between populations also included model, simultaneous release compounds, oxygen carbon dioxide. implementation has performed MATLAB software; calibration parameters was carried out genetic algorithms. ABACO allows one simulate dynamics components system, relative proportions bacteria, percentage each microbial population obtained with confirmed by respirometric techniques. powerful tool development microalgae-related processes, both maximize production microalgal biomass optimize capacity.
