PFAS DON'T BREAK DOWN. UNTIL NOW.
Per- and polyfluoroalkyl substances resist every conventional treatment technology. Electrochemical oxidation with boron-doped diamond electrodes breaks the C–F bond — the strongest bond in organic chemistry — directly at the electrode surface.
The Bond. The Regulation. The Solution.
The C–F Bond Won't Break.
The carbon–fluorine bond is the strongest bond in organic chemistry — bond dissociation energy of ~485 kJ/mol. Conventional oxidants (chlorine, ozone, UV, permanganate) lack the energy to cleave it. Biological treatment ignores it entirely. Granular activated carbon and ion exchange capture PFAS but generate contaminated waste streams — they don't destroy the molecule.
Zero Discharge Is the Direction.
The EPA's 2024 PFAS MCL rule set enforceable limits for the first time. 4 ppt for PFOA and PFOS. PFAS is now on EPA's CERCLA hazardous substance list. State-level standards in Texas, Oklahoma, and across the country are tightening. Industrial dischargers, landfill leachate operators, and military site remediators are already under consent orders.
Mineralization, Not Concentration.
Electrochemical oxidation with boron-doped diamond electrodes generates hydroxyl radicals with oxidation potential of 2.8 V — enough energy to cleave the C–F bond directly. PFAS is not captured and concentrated; it is converted to carbon dioxide, fluoride ions, and water. No contaminated waste stream to manage downstream.
EOx Reaction at the BDD Electrode
Electrochemical oxidation is not a separation process — it is a destruction process. PFAS molecules are broken apart at the electrode surface into harmless inorganic end-products.
Hydroxyl radicals attack and cleave the C–F bond — the PFAS molecule disassembles into inorganic end-products. No PFAS in the effluent, no concentrated waste stream to manage.

Four Industrial Applications
PFAS-Contaminated Wastewater
Industrial process discharge, landfill leachate, and groundwater remediation streams. Polish to non-detect or compliance limits without generating a concentrated reject. Integrates downstream of pretreatment or as a final polish before discharge.
IX / GAC Regeneration Brines
The "destroy-the-concentrate" problem. When IX or GAC pulls PFAS out of a feed water, the regeneration brine becomes a hazardous waste. EOx mineralizes the concentrate so the only downstream stream is salt water.
RO Reject Streams
RO concentrates PFAS into a smaller-volume reject — still contaminated, still requires disposal. EOx polishes the RO reject to destruction-grade end-products, enabling zero-liquid-discharge designs without permanent waste.
AFFF / Aqueous Film-Forming Foam Sites
Military bases, airports, and fire training sites with legacy PFOA/PFOS contamination from AFFF use. Site groundwater treatment and on-site destruction of stockpiled AFFF foam, eliminating disposal liability.
The Compliance Clock Has Started.
EPA PFAS MCL (2024): 4 ppt MCL for PFOA and PFOS in drinking water systems. Five-year compliance window for monitoring; eight years for treatment installation. · CERCLA: PFOA and PFOS designated hazardous substances — Superfund-grade liability for releases and historical disposal. · EPA Method 1633: 40 PFAS compounds in wastewater, surface water, sediment, biosolids; pretreatment standards under development. · State levels in Texas, Oklahoma, Missouri, Louisiana, and Arkansas are tightening with various enforcement timelines.
Where We've Deployed EOx
Beyond PFAS, BDD electrochemical oxidation handles a wide range of recalcitrant industrial waste streams.
From Bench Test to Industrial Scale
We start with bench-scale testing on your actual wastewater — confirms the chemistry before any capital commitment. Field-scale systems are skidded, modular, and integrate into existing treatment trains.
PFAS in Your Discharge? Test, Don't Guess.
Send us a sample of your wastewater. We run bench-scale EOx, characterize PFAS destruction at multiple current densities, and write up an honest assessment of what a field-scale system would look like and what it would cost to run. No charge for the bench work.
