Cloth Filter and Membranes Pilot Testing at the Hale Avenue Resource Recovery Facility

The City of Escondido (City) is actively engaged in evaluating various options for ensuring adequate capacity at its Hale Avenue Resource Recovery Facility (HARRF.) The City is also interested in evaluating tertiary filtration technologies for upgrading existing continuous backwashing sand filters. In addition, the City is interested in evaluating long-term options, namely membrane technologies, for potential future indirect potable reuse (IPR) and other purposes. Brown and Caldwell was retained to conduct a pilot test of cloth-media filtration and ultrafiltration/reverse osmosis (UF/RO.) The pilot test was conducted over a 3-month period in Spring 2010. This paper will discuss the goals and objectives of the pilot test, discuss the operational issues encountered, and present the results of the pilot test.
