Numerical Simulation of Phycoremediation for Nutrient Removal Using the Extended Monod Model with Saulyev Technique

Abstract

Nowadays, as water pollution is increasing from agricultural sectors due to nitrogen and phosphorus, phycoremediation is used to remove nutrients with microalgae. In this paper, a mathematical model is developed to use the extended Monod model to analyze the growth of microalgae that have adsorbed nutrients by considering various flow velocities and levels of nitrogen as effects of biomass concentration. This model has been calculated with the numerical finite difference method using the Saulyev technique. Numerical simulations show results for various scenarios with flow velocities and levels of nitrogen that affect the growth of microalgae.
