Study of the solution for disinfection by supplying residual chlorine in the distribution networks of drinking water

Abstract

This paper proposes a solution to ensure quality of drinking water in water supply network by increasing chlorine concentration, reaching concentration level to disinfect water according to Ministry of Health regulation for water supply. Specifically, this study has been carried out at Tan Kien water supply station, Binh Chanh district, Ho Chi Minh City, by installing an additional chlorine station along the pipeline. As a result, after installation, the residual chlorine concentration has reached required concentration and has maintained the stability of its level. The chlorine station is an integrated, compact solution suitable for similar water supply areas: far from water supply plants, inadequate chlorine concentration and limited space for installation of chlorine system.
