Effect of turbidity on survival of Escherichia coli, feacal coliform and total coliform in grey water by using solar disinfection (SODIS)

Abstract

Abstract Tropical country like India can use an alternative disinfection option to utilize solar energy for disinfecting grey before reuse. This study was aimed to conduct experiments to examine the impact of turbidity (75NTU, 50NTU and 30 NTU). This experiments were carried to inactivate EC (Escherichia Coli), FC (Feacal Coliform) and TC (Total Coliform) at different flow-rate (33.4, 44.3, 66.8, 135, 268 and 555 ml/min) by solar radiation intensity. It was observed that as turbidity and flow-rate as goes on decreasing inactivation of bacteria goes on increasing.
