Effect of phytochemicals under variable disinfection conditions on heterotrophic bacteria in canal water/

Abstract

Availability of decontaminated and clean drinking water determines the living standard of individuals. Provision of clean drinking water appearing as a major problem because of increased population level. In this work, cost effective and energy efficient solar disinfection technique was applied for the disinfection of Heterotrophic bacteria. Phytochemicals were added to enhance the disinfection efficiency because solar light is a variable source. Sample was taken from canal water and exposed to sunlight in the presence of phytochemicals and viable colonies were counted after incubation period. Study was carried out with various concentrations of different phytochemicals and variable environmental conditions. Almost 70-75% efficacy of bacterial disinfection was achieved.
