Pipeline Flash Reactors (PFRs) utilize high-velocity mixing to transfer ozone or oxygen-enriched sidestreams into bulk water flow, all within a compact footprint. With a PFR, ozone or oxygen mass transfer occurs within seconds and eliminates the need for additional tanks or basins. Whether it is providing ozone for water purification or increased dissolved oxygen for wastewater, Mazzei's PFR uniformly distributes gas into water and minimizes the size and cost of gas contacting.
