Description
Population increases within the city of Ormond Beach, Florida, placed increased demands on the city’sexisting 8 mgd conventional lime softening water treatment plant. Combinedwith deteriorating raw water quality due to salt water intrusion and upconing, the city decided on a low pressure reverse osmosis (LPRO) expansion. In January 2008, the expansion was first placedonline and all construction activities concluded a few months later. The successful permitting of an innovative and sustainable method of managing up to 1.0 mgdof concentrate produced by Ormond Beach’s LPRO expansion was made possible by a collaborativeeffort by the city, the Florida Department of Environmental Protection (FDEP), and CDM. This uniquemethod of concentrate management provided for the blending of the LPRO concentrate with reclaimedwater at the city’s WWTP. The most significant benefit associated with thisconcentrate management strategy was the ability to reuse this previously unutilized resource andaugment reclaimed water supplies without consuming treatment capacity of the WWTP. This paper discusses the permitting efforts and challenges associated with theimplementation of this innovative method of concentrate management, the first 17 months of operatingdata, and lessons learned throughout the course of this project. Includes tables, figures.
