Simulation platform for in-situ Fe(II) oxidation and bioscorodite crystallization in a one-step process for As(V) immobilization from acid wastewater

Abstract Crystalline scorodite is considered one of the safest materials available for the removal and disposal of arsenic. Its formation by biological means represents a promising solution for the treatment of acidic wastewater containing arsenic. In this study, an analysis of the processes that take place in a bioreactor for the biogenic scorodite crystallization was performed using mathematical modeling. The model was fitted to a set of experimental data, including batch and continuous bioreactors using two different thermoacidophilic archaeal strains, showing a successful model prediction capability (0.85
