Modelling and Simulation of Pollutant Transport in Porous Media—A Simulation and Validation Study
In this paper, the transport of pollutants is simulated with COMSOL multiphysics in a transition-based cross-sectional model to trace the path and flow of pollutants after infiltration from the point of discharge of treated domestic sewage. The study is investigated using soil columns with known porosity and permeability and with various other boundary conditions. The solutions are tested using a finite-element numerical model built with COMSOL Multi-physics. It is found that the simulation model holds good in pollutant removal in comparison with the physical pilot scale model. It is also found that there is a strong correlation between the inlet and outlet parameters in removing the pollutants with naturally available media (soil). Also, the removal efficiency in BOD and COD in soil media is 54.54 mg/l and 50.13 mg/l respectively. The results of the reliability check also showed good agreement between the measured and the simulated value for both BOD and COD with (R2 = 0.83), (R2 = 0.99), respectively. Hence the results obtained from horizontal transport of pollutant is more significant.
