City of Boca Raton?s NF Plant: A Plant History

This paper gives a history of the 40 MGD NanoFiltration (NF) Water Treatment facility at the City of Boca Raton, Florida that has operated since August 2004. . The original membranes lasted ten years and were replaced with the next generation of low fouling NF membranes. The new low fouling NF elements started up at only 63 psi for an initial 24% energy savings. The initial design based on pilot testing eliminated the need for pretreatment chemicals for annual cost savings.
