AWWA JAW17363

The design of the Los Angeles Aqueduct Filtration Plant currently under construction calls for pretreatment with ozone to aid in flocculation, to control tastes and odors, to reduce the production of trihalomethanes, to serve as a disinfectant, and to aid in the removal of turbidity. Specifications for the ozone system allowed bidders to choose among four alternative methods for ozone production and postponed the final design of the building housing the ozone system until the equipment had been selected. In addition to bid proposals, bidders were required to supply specific data to ensure a costeffective facility over a life cycle of twenty years and evidence of experience with ozone systems of comparable size. The successful bidder offered a system designed around a high-purity oxygen-feed system with on-site oxygen generation by means of a cryogenic generator. It is estimated that the city of Los Angeles will save $5 million over the next twenty years as a result of this unusual bidding procedure. Includes 8 references, table, figures.
