Description:
U.S. EPA coordinated a field study with South Mesa Water Utility to look for treatment alternatives for California State Project Water in the small community of Calimesa, California. EPA evaluated the performance of a system comprised of Radial Flow Fluidized Filtration (R3f) followed by microfiltration (MF) and ultrafiltration (UF) through a series of turbidity and microbial challenges. The R3f and MF-UF system was challenged to remove turbidity, particles, and bacteria and viral surrogates (B. Subtilis, MS-2) from State Project Water. Turbidity, particle counts and Total Organic Carbon (TOC) were also monitored to obtain additional information on the performance and maintenance requirements of the systems. The report documents the results of these tests and also summarizes the critical observations on the maintenance of the R3f-MF-UF system and the use of turbidity and particle count as a surrogate for measuring the performance of the treatment plant.
