Mazzei Injector Company, LLC products

Mazzei venturi injectors are differential pressure injectors featuring internal mixing vanes. The patented design and precise construction optimize injector efficiency, suction capacity, and mixing capabilities. With no moving parts, maintenance is simplified, resulting in significantly lower operating costs compared to less efficient systems.

Mazzei sidestream injection systems are designed using our patented technologies to obtain the most efficient mixing and contacting of air, oxygen, ozone or chemicals into a water stream.

Mazzei Mass Transfer Multiplier (MTM) mixing nozzles provide dynamic mixing under pressure, leading to superior mass transfer. When paired with a Mazzei injector, these nozzles significantly boost system mixing and contacting performance. With Mazzei MTM nozzles, treatment gases can be delivered to any depth—all within a compact design with trouble-free operation and easy installation. Many models are available to cater to various applications, providing versatility and performance.

The Mazzei 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. Mixing and contacting are then enhanced in a Mazzei Flash Reactor. From there, the two-phase flow travels to a degas separator and degas relief valve for additional mixing and entrained gas removal. Finally, Mazzei Mass Transfer Multiplier (MTM) mixing nozzles force dissolved ozone flow into untreated water in a pipeline or basin for thorough mixing.

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.

The degas separator, an integral component of the Mazzei GDT system, is a patented centrifugal vortex unit designed to separate entrained and stripped gases—such as ozone, chlorine, or methane—from water, based on the density difference between the gas and liquid. Its unique, compact design quickly and effectively separates entrained gases 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.

High-dosage ozone system designs, such as those required by some water reuse projects, place extraordinary demands on an ozone mass transfer system. Mazzei listened to consulting engineers, utility operators, environmental regulators and contractors to learn their diverse needs for extremely high-efficiency ozone mixing systems.

As an integral component of the Mazzei GDT system, the degas relief valve is engineered to facilitate the automatic release of undissolved gases accumulated within a degas separator when it reaches capacity. During operation of the separator under pressure, the degas relief valve safely vents the gas for processing or releases it to the atmosphere.

The Mazzei Chemical Mixing Reactor (CMR) was specifically designed to rapidly mix coagulants into a mainline flow. The CMR is based on Mazzei’s successful Pipeline Flash Reactor (PFR), a proven solution for mixing and contacting which has been installed in numerous municipal facilities worldwide.
