The Englewood Water District (EWD) located in Englewood, Florida operates a brackish
water reverse osmosis (RO) desalting facility with nearly 25 years of operating history and
treatment technology "firsts" and process advances. Numerous studies, improvements, and
expansions over the years have improved RO performance and reduced energy
consumption. Some of the advances that are discussed in this paper include:
development of site-specific, membrane-specific flux criteria;
innovative bacterial fouling study and fouling control remedial measure;
energy recovery and membrane stage flux-balancing methods;
use of three generations of spiral wound RO membrane elements; and,
innovative RO train design features to maximize performance and minimize costs
with increasing feed water salinity from an initial 4,700 mg/L TDS to current values
seen in some wells of approximately 8,000 mg/L.
This paper summarizes the history of the EWD RO plant and describes the process
advances, some of which have had an impact not only on the Englewood facility, but on the
membrane industry in general. Includes 5 references, tables, figure.
