Mazzei offers complete ozone systems, in addition to pressurized gas-liquid mass transfer components for rapid oxygen, CO2 and ozone dissolution. Mazzei ozone systems feature onsite oxygen production and ozone generation, GDTTM transfer skid, instrumentation and PLC PID loop control in a high-efficiency, small-footprint, low-maintenance package. more
  • Mazzei offers complete ozone systems, in addition to pressurized gas-liquid mass transfer components for rapid oxygen, CO2 and ozone dissolution. Mazzei ozone systems feature onsite oxygen production and ozone generation, GDTTM transfer skid, instrumentation and PLC PID loop control in a high-efficiency, small-footprint, low-maintenance package. more
  • Mazzei’s wastewater AirJection aeration system is an efficient, low-cost, quiet solution. Wastewater is circulated through patented Mazzei injectors, creating a vacuum to draw air into the wastewater. The aerated process water is discharged back into the tank through patented Mazzei nozzles for additional oxygen transfer and mixing. more
  • Mazzei Venturi injectors are differential-pressure injectors with internal mixing vanes. The unique, patented design of Mazzei injectors permits them to start suction when the outlet pressure is only 20% lower than the inlet pressure (in most models). Because of the high efficiency of Mazzei injectors, operating costs are lower than with less efficient systems, and they are trouble-free... more
  • Mazzei Mass Transfer Multiplier (MTM) mixing nozzles provide dynamic mixing under pressure, which results in greater mass transfer. When used in conjunction with the patented Mazzei injector, these nozzles dramatically enhance system-contacting performance. Mazzei nozzles allow the delivery of treatment gases to any depth—all within a compact design with trouble-free operation and easy... more
  • 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... more
  • The GDT degas separator uses a patented centrifugal process to quickly and effectively remove unwanted entrained and stripped gases from pressurized water systems. Its unique compact design quickly and effectively separates unwanted entrained gases—such as ozone, chlorine and methane—and requires far less space than traditional gas separators. It enables gas separation with pressure differentials... more
