K. Deepa ABSTRACT Treated municipal wastewater is used as an input water source for recharge of groundwater using the Soil Aquifer Treatment (SAT) method. The aim of this study is to assess the treated waste water quality performance before and after SAT by using short term soil column development for aquifer recharge applications. The water quality parameters considered during, before, and after SAT are Biological Oxygen Demand, pH, Total Suspended Solids (TSS), Nitrite and Nitrate. The quality of effluents is improved after passage through the soil layers in the soil columns. The final effluent quality from the soil columns of the different sites show different performance percentages. The infiltration rate varied in all soil columns due to development of clogging layer at the top of the soils. Reference: Deepa, K., and.M. Krishnaveni. 2012.
