Ultraviolet Disinfection for Wastewater: Low-Dose Application Guidance for Secondary and Tertiary Discharges Water Environment Federation

Publisher Marketing: Developed in conjunction with the International Ultraviolet Association, Ultraviolet Disinfection for Wastewater: Low-Dose Application Guidance for Secondary and Tertiary Discharges serves as a guide for consultants, wastewater utilities, and operators and provides introductory information on the advantages (and disadvantages) of UV disinfection compared to other commonly used technologies. It also provides valuable information to regulatory agencies who review applications for the use of UV disinfection systems in water resource recovery facilities that are subject to discharge limits for bacteria under National Pollutant Discharge Elimination System permitting. Providing specific case study examples, UV Disinfection fills an existing gap in the design guidance that is available for UV disinfection for low-dose applications, which includes disinfection of secondary and tertiary wastewater effluent discharges to meet NPDES compliance.

However, it is NOT a Manual of Practice. The manual represents the wisdom, experience, and hard work of more than 200 subject matter experts, staff, and members from each of these three partner organizations. Many of the chapter lead authors are senior individuals who will soon be retiring from the profession.
