A High Voltage Pulse Generator for Ozofractionation based PFAS Treatment in Industrial Waste

The presence of PFAS is significant in industrial waste and has been dubbed as possibly carcinogenic to humans. The ozofractionation based treatment is more efficient in removing PFAS from industrial waste. The ozofractionation process comprises of ozone being applied to the waste water in the form of tiny bubbles. The PFAS comes under heavily contaminated waste, and removing it requires higher amount of ozone; hence the power requirement is typically high for an ozone generator used for PFAS treatment. This paper proposes a novel silent discharge based high-voltage pulsed ozone generator topology for ozofractionation based removal of PFAS. A novel converter topology i.e. full bridge-based resonant boost, is proposed in this paper. The converter topology is generates high voltage pulses of 5kV (Peak-Peak), with pulse width (FWHM) of 4µs and PRR of 15kHz. The proposed topology is analyzed, modelled and designed, and the same is verified through simulation results.
