Abstract

The increasing number of microalgae-based applications demands the development of model-based information and decision support systems that can deal with their complex behavior, particularly the interactions in mixed algal-bacterial wastewater treatment systems. This work aimed to estimate the parameters for modeling and simulating an anoxic-aerobic algal-bacterial photobioreactor with biomass recycling for treating high-strength wastewater. Estimating the model parameters was critical in applying the model to anoxic-aerobic algal-bacterial systems. Process model and simulation were developed using the dynamic simulation software PROOSIS®. The model was set up and then calibrated with data from a lab-scale plant treating different dilutions of digestate. Simulations and model performance metrics validated the capability of the calibrated mathematical model to predict the experimental results.

期刊介绍： Algal Research is an international phycology journal covering all areas of emerging technologies in algae biology, biomass production, cultivation, harvesting, extraction, bioproducts, biorefinery, engineering, and econometrics. Algae is defined to include cyanobacteria, microalgae, and protists and symbionts of interest in biotechnology. The journal publishes original research and reviews for the following scope: algal biology, including but not exclusive to: phylogeny, biodiversity, molecular traits, metabolic regulation, and genetic engineering, algal cultivation, e.g. phototrophic systems, heterotrophic systems, and mixotrophic systems, algal harvesting and extraction systems, biotechnology to convert algal biomass and components into biofuels and bioproducts, e.g., nutraceuticals, pharmaceuticals, animal feed, plastics, etc. algal products and their economic assessment
