Iron removal for chilled water systems

Our patented Halbach-array magnetic treatment aggregates fine iron oxide for capture by downstream filtration.

01 / Installation

Where it installs

We install it on side-stream filter piping, or upstream of sand filters in a bypass loop. The magnetic field promotes iron aggregation so particles can be captured by existing filtration.

What a trial can measure

Mass capture: Grams captured per 1,000 gallons filtered
Flow rate: Treated vs control leg comparison
Iron concentration: PPM trend via lab sampling
Differential pressure: Filter loading trend over time
Site context: Approved secondary measures when applicable

Field observations

Bag filter saturated with iron oxide precipitate; iron-rich material observed near magnetic treatment devices
Iron at LAX was reduced from 3.9 ppm to 0.51 ppm
Two-filter test/control series used flow totalization and weighed filters for validation
HydroFlux is not a biocide, so microbial outcomes need their own testing at your site

Planning your trial

We agree on success measures before testing. Where practical, we compare treated and untreated water under similar conditions. We record cleaning, filter changes and other operating changes when assessing the result.
