Irvine Ranch Water District (IRWD) was one of the first water suppliers to
pioneer the installation of the dual plumbing systems in high rise office
buildings located in south Orange County, California. Currently, the recycled
water blend from the District's water reclamation plant and open storage
reservoirs is used in the high rise buildings for toilet flushing. Most of the
high rise buildings are equipped with pleated cartridge filtration systems
sensitive to fluctuations of the influent water quality. However, these systems
are prone to plugging, breakdowns and high maintenance costs. The objective
of this project was to find suitable filtration systems with lower maintenance
costs for high rise buildings. Initially, IRWD identified two technologies for
excess turbidity removal in high rise buildings. One was a bag filter technology
utilizing multilayer polypropylene or polyester and nylon, high loading capacity,
double length bag filter elements arranged in fiberglass or steel cylinder
housings. The other was a self-cleaning automated filter process, utilizing a
drum with backwashable cassettes and a sophisticated high pressure rinse system.
This paper presents the results of pilot testing which determined that bag
filtration might be the most efficient and feasible system for the high rise
building applications. Includes 4 references, tables, figures.
