2018 IUVA Americas Conference Workshop
Monday, February 26, 2018
1:00 PM - 5:00 PM
UV Fundamentals, Design Considerations, Applications, and Opportunities
The purpose of this workshop is to provide a basic understanding of UV fundamentals, along with an overview of UV considerations, applications, and case studies across water, wastewater and reuse. Additionally, special applications of UV will be presented, including a discussion on the science and application of UV-AOP, as well as a look into the future research that is needed for UV–chlorine AOP.

Details About the Facility:
Leo J. Vander Lans Water Treatment Facility located in Long Beach, California, owned by Water Replenishment District of Southern California, receives tertiary-treated water and provides a multi-barrier treatment through a process train that includes microfiltration (MF), reverse-osmosis (RO), and ultraviolet light (UV).
The facility was built in 2003 and subsequently expanded in late 2014. The expansion increased the facility's capacity from 3 million gallons per day to 8 million gallons per day, providing up to 100% of the demand for the seawater barrier. The 2014 facility expansion added an advanced oxidation process (AOP), which augments the existing UV system with the addition of hydrogen peroxide for removal of organics and enhanced disinfection and included unique treatment process enhancements to reduce the facility's waste generations. The process enhancements include (1) a third-stage RO to increase recovery from the original 85% to 92.5%; and (2) a MF backwash waste treatment system that recovers approximately 95% of the backwash waste stream through dissolve air flotation (DAF) treatment and a follow-up polishing MF. With these process enhancements, the facility has been expanded to almost triple the production capacity without any increases in waste generations.
The Long Beach Water Department is responsible for operation and maintenance of the treatment plant under contract with WRD.
