**4. Media characteristics**

Soil is used as media for the recharge in the physical model developed. The media characteristics such as permeability, porosity, grain size, specific gravity, and density are the parameters determined.

The table indicates the.


*Study on the Impact of Artificial Recharge on Treated Domestic Sewage DOI: http://dx.doi.org/10.5772/intechopen.109868*


From the results, it was observed that there is a considerable reduction in the pollutant concentration from inlet to outlet which shows the impact of artificial recharge. Further, it is observed that the pollutant removal efficiency is higher in soil media than in sand media. Hence for the prediction analysis, the properties of soil are considered in the simulation model (COMSOL Multiphysics) [7].
