Closed Vessel Ultraviolet (UV) Technology For Municipal Wastewater

Ultraviolet (UV) disinfection is now a standard feature in many wastewater utilities. The technology is widely favored due to its non-chemical nature, the fact that no subsequent de-chlorination process is required, and its ability to be unselective in disinfection performance. Throughout the years, the focus in municipal wastewater is to install UV in an open channel. However, there are alternative solutions to achieve required disinfection. The purpose is to give engineers and municipalities information regarding other forms of successfully operating ultraviolet disinfection systems instead of designing around the "traditional open channel" types of UV disinfection.
