Full Description

The City of Boca Raton, Florida is currently constructing a 40-mgd nanofiltration plant.This will be the largest plant of its kind in the world when it is commissioned in late2003. This paper focuses on design issues for this plant and the results of extensive pilotand bench-scale tests. The pilot and bench-scale tests were conducted to find ways toreduce the severe fouling caused by the very high organic content of the raw groundwater. Some interesting results from the testing are discussed including zeta potentialand electrophoretic testing, side-by-side comparisons of various membranes andantiscalants, and the introduction of a new low fouling nanofiltration membranetechnology. Includes table, figures.
