MODELING FOR METALS CONTAMINATED WASTEWATER BY ALGEA ADSORPTION

Abstract

We studied the ability of adsorption of algae in wastewater polluted by alloys. A mathematical model is developed to describe the biosorption of metals by algae in the contaminated water. The analytic solution is obtained by using Similarity method. The result provides understanding the advection and diffusion of the metals in the contaminated water at various times and positions. It was found that the concentration of metals in the contaminated water consisting of the algae decreases over time and asymptotically reaches the equilibrium state. Moreover, the analytic results were validated by comparing with experimental data. This work is expected to greatly benefit an environmental science particularly concerning the wastewater treatment.
