In May 1999, the City of Boca Raton and the CDM design team began design of a 40
million gallon per day (mgd) capacity nanofiltration process addition to the City's
existing 70 mgd conventional lime softening process at the Glades Road Water Treatment
Plant. The primary objective of the project was to maintain continued compliance with
the disinfectant/disinfection byproduct (D/DBP) rule (i.e., reduce total trihalomethanes and haloacetic acids), and improve the level of service to the Boca Raton
customers by significantly improving the color in the blended finished water. The start-up phase for the nanofiltration process was initiated in August 2004. Due to the
large size of this facility, and the fact that it was starting up without chemical
pretreatment, the construction contract provided for a cautious, phased start-up program.
Start-up of the process was planned to take place one unit at a time over a six-month
period. The full 40-mgd capacity was scheduled to come on line with the start-up of the
twelfth and last skid.
During start-up and the first year of plant operation, membrane performance was fine-tuned,
and several other process optimization efforts were undertaken. This paper
discusses the start-up experience relative to these topics. Includes tables, figures.
