This presentation provides an overview of regulatory
considerations, the fundamental principles of UV disinfection and how these
factors impact the design, operations and maintenance of UV systems for
wastewater disinfection. In addition, a case study is presented on the
selection of UV disinfection for the City of Jefferson, Missouri, which was
faced with a permit modification that required seasonal disinfection of their
wastewater effluent. The City with their consultant, evaluated various
disinfection technologies, with low pressure, high output UV disinfection
being the most cost effective. The system has been completed and is
operational; lessons learned regarding maintenance, operations, and general
functionality of the UV will be presented.
