College, Nashik, India > Research Paper 2017 4 30 2017 06 2 Obtaining clean drinking water is a constant challenge in many communities in developing countries. The contaminated water causes many gastrointestinal illnesses. The vast majority of such diseases are recorded in rural areas of developing countries where there is lack of adequate sanitation facilities and the water supply is contaminated with a variety pathogenic and nonpathogenic organisms. The present research work attempts to identify and characterize the inactivation process in operation when contaminated drinking water is stored in transparent PET bottles and exposed to sunlight. The role of solar radiations in activation mechanisms were studied in detail by measuring water temperature, light intensity, pH, turbidity and MPN which were recorded during a series of solar disinfection procedures carried out at Nashik city. The highest light intensity and temperature are responsible for the change in physicochemical property of water as well as MPN and MPN reduction efficiency. The results showed the maximum MPN reduction efficiency of 71.43%, at the temperature of 48.70C and 5 hours’ exposure to solar radiations. Copyright@ International Science Community Association
