UV Light Exposure Over 120 Seconds Was Better At Reducing E. Coli in Contaminated Water

The UV light as a method of disinfection of water is an alternative for inactivation of microorganisms that may be present in water. Considering the importance of the microbiological quality of water for human consumption and the restrictions on drinking water in many areas with poverty, the present experiment aims to simulate solar disinfection with an UV light lamp. For that reason, we wanted to demonstrate the efficiency of UV light as a method of disinfection of pathogens in water so that this method could be replicated by anyone and improve the quality of life for people in needy areas.
