This powerpoint presentation begins by providing a brief overview of the Startex Jackson Wellford Duncan (SJWD) Water
District located in
Spartanburg County, South Carolina. A 2008 master plan and capital improvements
program recommendation is presented, along with pilot testing objectives that include the following: determine most appropriate technology for future
facilities;
evaluate inclined plate settler effectiveness with either
granular media filters or membrane filters;
compare performance of granular media filters vs.
membrane filters; and,
establish design and operating conditions for inclined
plate settlers, granular media filters, and membrane
filters for full-scale implementation. Pilot testing results are presented for plate settlers, granular media, and membranes, along with a technical and economic evaluation of
alternatives. Conclusions and recommendations included the following:
all technologies were capable of producing good water
quality if optimized;
inclined plate settler worked well, and the lower settled water turbidities (i.e. lower loading rates)
were likely more important for granular media filters than
membranes (0.3 gpm/sf versus 0.25 gpm/sf);
granular media filter
worked well - particulates and aesthetics, and was a
proven process; membranes were
more effective than granular media for particle removal; less effective than granular media for aesthetics;
effectiveness of raw water permanganate varied;
post-membrane contactor (pressure filter) should be considered;
membrane fouling (TCSF recovery); citric acid/hydrochloric acid required;
consider proof pilot during design; and,
slightly greater cost, but evaluation indicates greater
benefit. Includes tables, figures.
