Disinfection of Water and Wastewater

Course outline

The need for disinfection of drinking water is introduced along with the regulatory requirements followed by a brief examination of water borne diseases. Water quality parameters and their significance in disinfection and re-infection are discussed. A major part of the module is devoted to the method of chlorine disinfection including system design, performance, monitoring, control, de-chlorination and chloramination. The advantages and limitations of different methods of disinfection including ozone and UV are considered.
