How it works
PCDR uses pulsed corona discharge in a reducing atmosphere to destroy halogenated organic compounds at the molecular level. The high-voltage nanosecond pulses generate reactive plasma species that break carbon-fluorine and carbon-chlorine bonds — the strongest bonds in organic chemistry, responsible for the persistence of PFAS/PFOS and dioxins.
Key advantages
- Near-complete mineralization of PFAS/PFOS, including short-chain compounds resistant to other treatments
- Effective even in high-salinity and high-suspended-solids matrices (landfill leachate)
- No chemical additions required — plasma is generated from the atmosphere
- Scalable from laboratory to industrial flow rates
- Can be combined with PCDO for finishing treatment
Target contaminants
PCDR is specifically designed for halogenated persistent pollutants:
- Per- and polyfluoroalkyl substances (PFAS/PFOS) — including short-chain C4–C6
- Chlorinated and brominated organics
- Dioxins and furans (PCDD/PCDF)
- Chlorinated phenols and naphthalenes
Typical applications
| Industry | Challenge | Result |
|---|---|---|
| Landfill operators | PFAS/PFOS in leachate | >99% removal |
| Industrial wastewater | Dioxins and chlorophenols | Near-complete mineralization |
| Drinking water utilities | PFAS contamination | Below detection limit |
| Fire training sites | AFFF-related PFAS | Full destruction |
