Pipeline Flash Reactor

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 in the pipeline within seconds, eliminating the need for additional tanks or basins. Whether it is mixing ozone into water for 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 systems.

Venturi Injectors

Mazzei venturi injectors are differential pressure injectors with internal mixing vanes. The unique, patented design of Mazzei injectors maximizes injector efficiency, suction capacity and mixing capabilities. Our injectors also have no moving parts, which simplifies maintenance, and they have much lower operating costs than less efficient systems.

GDT System

The GDT™ process starts with the creation of ozone from an ozone generator. The ozone is then drawn into a Mazzei venturi injector, which provides dynamic mixing (a back pressure control valve adjusts injector outlet pressure optimizing ozone mass transfer in the system). Then, mixing and contacting is enhanced in a Mazzei Flash Reactor™. From there, the two-phase flow travels to the degas separator (DS) and degas relief valve for additional mixing and entrained gas removal. Finally, Mazzei Mass Transfer Multiplier (MTM) mixing nozzles force dissolved ozone flow into the untreated water in the pipeline or basin for thorough mixing.

Degas Separators

The degas separator, part of the Mazzei GDT^™ process, is a patented centrifugal vortex unit that separates entrained and stripped gases from liquid (water) based on the density difference between the gas and liquid. Its unique compact design quickly and effectively separates entrained gases—such as ozone, chlorine, or methane—and requires far less space than traditional gas separators. It enables gas separation with pressure differentials of 5% or lower and at variable flows. The self-cleaning design significantly reduces maintenance and downtime, and it includes no moving parts that can wear out, break down, or require service.
