    Case study

    LAX Terminal 5

    For 10 months we ran HydroFlux on the chilled water system at the LAX Central Utility Plant, measuring iron, filter capture and day-to-day operations.

    System
    Closed-loop chilled water
    Location
    LAX Central Utility Plant
    Duration
    10 months
    Measurement
    Flow-normalized filter mass + Fe ppm

    In short

    01 / The challenge

    Why it mattered

    Iron deposits were building up in the chilled water equipment and adding to cleaning work. We installed HydroFlux on the side-stream filtration to capture that iron.

    02 / Results

    Field result

    Lower iron
    87%
    3.9 to 0.51 ppm

    From our LAX field report and the terminal’s iron sampling.

    03 / Field evidence

    What we found

    Five HydroFlux bracelets installed on Terminal 5 side stream pipe at LAX

    04 / Methodology and impact

    Test setup

    We installed the bracelets on the side-stream filtration, recorded flow and weighed the filters. The treated and untreated filters sat in different positions, so their conditions weren’t identical.

    What the study produced

    • Iron-rich material captured in the side-stream filter
    • Site measures for iron and filter loading, set up with the plant team
    • Improvements we now build into every trial
