Abstract

Advanced wastewater treatment using reverse osmosis (RO) technology has been conducted at Orange County Water District (OCWD) for more than 30 years. Continuing in its tradition of innovation, the district operates the Groundwater Replenishment System (GWRS), a 70-million-gallons-per-day (mgd) advanced wastewater purification facility in Fountain Valley, Calif. Considered an indirect potable reuse facility, the GWRS provides purified water for groundwater recharge and maintenance of a seawater intrusion barrier for protection of the groundwater basin. The GWRS is made up of three major treatment processes: microfiltration (MF), reverse osmosis (RO), and advanced oxidation (ultraviolet treatment with hydrogen peroxide). The article also examines conservation, maintenance, membranes, monitoring, and TOC.
