PIPELINE FLASH REACTOR™ FOR MIXING & CONTACTING
Pipeline Flash Reactors™ (PFRs or spool pieces) 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 in the pipeline within seconds, eliminating 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 the water and minimizes the size and cost of gas contacting.

The Best Performance for Ozone Transfer
The patented Pipeline Flash Reactor technology is supported by years of research at leading universities. It delivers superior ozone transfer performance with proven *mass transfer efficiency rates exceeding 95% with little measurable pressure loss across the mixing zone.
PFR Provides High Ozone Mass Transfer in a Small Footprint Design
Wastewater plants typically have to employ some method of treatment to increase dissolved oxygen prior to final discharge into receiving waters. Mazzei’s Pipeline Flash Reactor provides a technology for rapid oxygen transfer within a compact footprint. The system utilizes a small sidestream passed through a patented Mazzei venturi injector to draw in ambient air, concentrated oxygen or ozone. The aerated sidestream is then delivered to the Pipeline Flash Reactor where it aggressively mixes with the main flow, uniformly transferring the oxygen in the effluent pipeline.
Where space is an issue, such as in existing built-out urban areas, the PFR eliminates the need for post-treatment cascading systems or diffuser basins required by other technologies. The PFR can also be utilized for the dissolution of oxygen gas in systems with high dissolved oxygen requirements.
The Pipeline Flash Reactor eliminates noise and high maintenance costs and downtime associated with blowers and bubble diffusion basins as well as the problems that cascade systems have with flooding.
