Mazzei Injector
About
Mazzei Injector Company, founded in 1978 and based in Bakersfield, California, specializes in high-efficiency venturi injectors, flash reactors, and gas-liquid mixing systems for water and wastewater treatment. The company holds multiple U.S. and international patents, including U.S. Patent No. 12,251,672 for its Chemical Mixing Reactor. Mazzei's core technology is the venturi injector with internal mixing vanes — a differential-pressure-driven device with no moving parts that achieves gas and liquid injection at lower operating cost than pump-driven alternatives. The product portfolio includes the Pipeline Flash Reactor (PFR) and PFR+ for seconds-scale gas mass transfer in pipeline systems, the patented Chemical Mixing Reactor (CMR) for rapid coagulant mixing, standalone Flash Reactors for gas-liquid shearing, and the complete GDT (Gas Dissolution Technology) process chain integrating venturi injection, backpressure control, flash reactor, degas separator, and MTM nozzle manifold. Degas separators and relief valves handle gas-liquid separation, while injection skids and fertigation skids provide preassembled treatment packages. Mazzei serves municipal water treatment (ozonation, disinfection, coagulant mixing), wastewater (aeration, sewer main aeration), irrigation (AirJection, chemigation, fertigation), pool and spa (ozone contacting), aquaculture, and wine production (pump-over aeration). The company also offers computational fluid dynamics (CFD) modeling services for custom application optimization.
Key Products
