Full Description

This powerpoint presentation begins by providing a brief overview of the Startex Jackson Wellford Duncan (SJWD) WaterDistrict located inSpartanburg County, South Carolina. A 2008 master plan and capital improvementsprogram recommendation is presented, along with pilot testing objectives that include the following: determine most appropriate technology for futurefacilities;evaluate inclined plate settler effectiveness with eithergranular media filters or membrane filters;compare performance of granular media filters vs.membrane filters; and,establish design and operating conditions for inclinedplate settlers, granular media filters, and membranefilters for full-scale implementation. Pilot testing results are presented for plate settlers, granular media, and membranes, along with a technical and economic evaluation ofalternatives. Conclusions and recommendations included the following:all technologies were capable of producing good waterquality 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 thanmembranes (0.3 gpm/sf versus 0.25 gpm/sf);granular media filter worked well - particulates and aesthetics, and was aproven process; membranes weremore 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 greaterbenefit. Includes tables, figures.
