    Plant Replaces Aging GBTs with Sludge Thickening Centrifuges

    CaseStudy-SAWS-San-Antonio-TX-THK600

    Location: Steven M. Clouse San Antonio Water System (SAWS)  |  San Antonio, Texas
    Plant Size: 80 MGD
    Installation: 2019 (2) THK600 Sludge Thickeners

    OPERATING DATA
    • Feed @ 1.0-1.3% TS
    • 800 gpm average
    • 95% capture
    • 2.0-2.7 lbs/ton polymer, active
    • 0.09-0.11 kW/gpm
    • 6.5% TS TWAS

    PROBLEM

    SAWS had four aging GBTs that could not handle the increasing flows. The sludge feed was a blend of WAS and primary sludge from two plants — SM Clouse and Leon Creek. The THKs ability to reduce polymer consumption by 50% was a key factor for the equipment choice.

    RESULTS

    • Reduced polymer usage depending on seasonal usage, a savings of $100,000 to $400,000/yr
    • Eliminated the need for continuous wash water by replacing the GBTs with THKs
    • Enclosed THK system increased hygienic operation and safety for operators
