PARTICLE TRACKING MODEL OF SULPHUR DIOXIDE IN A FLOW THROUGH A POROUS MEDIUM | Journal of Applied

For more than four decades, the transfer of pollutants from localised sources such as factories and agricultural farms in porous media, known as hydro dispersion, has been a prominent topic. Inorganic wastes, primarily biodegradable and non-biodegradable substances such as sulphur dioxide, oil spills, human wastes, and fertilisers, percolates through porous media and eventually finds its way to water bodies such as streams, rivers, and boreholes as a result of industrial and agricultural activities. The goal of this research is to numerically describe a particle tracking model of sulphur dioxide in a flow through a porous media derived from Chemelil milling wastes (molasses) and agricultural inputs such as fertilisers, fungicides, and herbicides in terms of concentration between two points, concentration along the contour field, velocity, and decay and sorption effects in three dimensions. The three-dimensional non-linear advection-dispersion equation will be used to determine the governing equation of three-dimensional concentration distribution in fluid flow through porous media. The results will be validated using data from the Chemelil factory as the source point, and the Finite Difference Method will be employed to solve the problem.
