HOW IT WORKS
Inside the column
01
Ozone + air microbubbles
Ozone and/or air bubbles are introduced into a PFAS-contaminated stream inside an Olift® column, purpose-built for PFAS removal.
02
Hydrophilic/hydrophobic alignment
Each PFAS molecule has a hydrophilic head and hydrophobic tail, causing it to align and concentrate at the gas-water interface on the bubble surface.
03
Foam rises, water stays clean
PFAS-laden bubbles rise to form concentrated foam at the surface, leaving treated retentate behind with up to 99% targeted PFAS removal.
04
Foamate to destruction
The foam — just 1–10% of treated influent — is separated, collapsed, and concentrated, reducing the size and energy needs of Obreak® EO downstream.
THE MECHANISM
Hydrophilic heads, hydrophobic tails
WHY OLIFT™
Unique among air-only foam fractionation methods
Ozone microbubbles
More surface area than air-only bubbles, enhancing PFAS removal efficiencies.
Continuous operation
Runs continuously rather than in batches, for steady-state performance.
Fully automated
Remote operation and monitoring, with co-contaminant oxidation from ozone.
Broad source compatibility
Effective on RO concentrates, landfill leachate, groundwater, and drinking water.
WHERE IT WORKS
Effective across diverse PFAS-contaminated water sources
RO Concentrates
Landfill Leachates
Industrial Wastewater
Military Wastes
Groundwater
Drinking Water
Integrates into most existing flow sheets for PFAS removal and concentration — as a standalone step or paired with Obreak® Electro-Oxidation for complete onsite destruction.
PROVEN PERFORMANCE
Comparison of air vs. ozone in continuous foam fractionation
INTEGRATED SOLUTIONS
Pairs with Obreak® Electro-Oxidation for complete onsite removal, concentration, and destruction.
CASE STUDY
Onsite PFAS removal for landfill leachate at PVSC
Passaic Valley Sewerage Commission piloted E2METRIX’s closed-loop Olift® + Obreak® system on trucked-in landfill leachate — Olift’s staged foam fractionation concentrated PFAS into a fraction of the original volume before destruction.
