Dispersion of non Reactive Solute Through Perungudi Soil

摘要

An experimental study is conducted to investigate the dispersion of non reactive solute present in leachate through soil media at a municipal solid waste disposal site under saturated conditions.An experimental study is conducted to investigate the dispersion of non reactive solute present in leachate through soil media at a municipal solid waste disposal site under saturated conditions. The dispersion coefficient is found using NaCl as a tracer. Breakthrough curves are obtained for the three types of soil present in the Perungudi dumping site. Dispersion coefficient values are obtained by fitting the convection dispersion equation to the observed breakthrough curves for the chloride test at various depths. The values can be used to predict the movement of non reactive pollutants through the soil media and its ultimate effect on ground water. It is found that dispersivity values for non reactive solutes are independent of the depth in the soil columns. These values help to model the movement of non reactive solutes present in solid waste leachate through the soil media.
