How it works
PCDO uses pulsed corona discharge in an oxidative atmosphere to generate ozone, hydroxyl radicals, and other reactive oxygen species. These powerful oxidants attack and break down organic molecules that resist conventional biological treatment.
Key advantages
- Broad-spectrum effectiveness against refractory organics
- Full disinfection — inactivates bacteria, viruses, fungi, protozoa, and spores
- Removes colour, odour, and reduces TOC
- No chemical residuals — all oxidants decompose to oxygen and water
- Can be used standalone or as finishing stage after PCDR
Target contaminants
- Refractory organic compounds (difficult-to-biodegrade)
- Pharmaceutical residues (antibiotics, hormones, cytostatics)
- Dyes and surfactants
- Pathogens — full spectrum sterilization
- VOCs and solvents
- Phenols and aromatic compounds
