The City of San Diego is in the process of revising their Water Reuse Master Plan to include an
evaluation of all options for the use of recycled water to meet current and future water supply and
reuse needs. Some recycled water use alternatives, such as raw water reservoir augmentation, would
require a much higher water quality than is currently available. To evaluate whether the required
water quality could be achieved, the City conducted an 18-month (July 2004 ¿¿¿¿¿¿¿¿ December 2005) pilot
testing program of an advanced water treatment (AWT) train. The AWT consisted of three treatment
steps: ultrafiltration (UF); reverse osmosis (RO); and ultraviolet (UV) light + hydrogen peroxide.
This testing program evaluated the water quality performance of the AWT train during operation on
tertiary water from the City's North City Water Reclamation Plant (NCWRP). The testing program
also evaluated new generation RO membranes designed for water reuse, assessed several indirect
and direct RO membrane integrity monitoring methods and determined the impact of advanced
oxidation (UV + hydrogen peroxide) on select endocrine disrupting compounds (EDCs), and
pharmaceuticals and personal care products (PPCPs). This paper focuses on the operational and
water quality performance of the RO system. Includes 2 references, tables, figures.
