ABSTRACT

Water with good quality and sufficient quantity is essential for life. In the developing countries with poor sanitation and treatment opportunities, small scaled treatment alternatives are required, and the exposure of water to sunlight radiation was enhanced water quality. The solar disinfection of water (SODIS) is a technique used to inactivate microbes by sunlight. Energy from the sun is available abundantly in tropical country like India. The main objectives of this study: (1) To determine the efficiency of radiation intensity rate on the inactivation rate (2) To determine SODIS inactivation kinetics of Total Coliform. The result of the experiment shows that there is a reduction in Total coliform (79.2%), Turbidity (66.67%), TDS (41.03%) and EC (40.67%) after exposing the sample for 8 hours (one day) on sunlight.

Keywords: Solar radiation, Microbes, SODIS, low budget water purification
