Microbial activity (assisted by the urease enzyme) is used in a biogeochemical process known as MICP to precipitate calcium carbonate. Carbon sequestration, soil stability, and environmental remediation are just a few of the technical and engineering applications for this procedure. This study investigates the spatial distribution of calcium carbonate (CaCO3) during the Microbial-Induced Calcium Precipitation (MICP) process using COMSOL-Multiphysics software. A comprehensive model was developed to simulate the transport and reaction dynamics of calcium ions and carbonate species in a porous medium using crucial parameters such as microbial growth rates, reaction kinetics/rates, nutrient supply rates, and diffusion coefficients. The simulation's results highlight the intricate spatial patterns of CaCO₃ precipitation and the impact of microbial activity on the gradients in medium concentration and distribution. Research shows that calcium carbonate formation patterns function based on microbial activity strength through colonial concentration and dependence on solution concentrations of biological elements and cementation materials. This paper delivers helpful data to enhance bioremediation tactics along with calcium carbonate-based (ureolytic enzyme) therapy effectiveness and deepens our grasp of the MICP methodology. The research objective focuses on creating simplified models from earlier studies through proper implementation of the complex process inside COMSOL-Multiphysics software.
