Mazzei was founded in 1978 and has set industry standards for innovation and technology ever since. We manufacture a broad line of patented high-efficiency Venturi Injectors, specialized Mixing Nozzles, Degas Separators, Flash Reactors, and GDT Contacting Systems.

Our Mission

Mazzei is dedicated to conducting business with honesty, integrity and responsiveness in the development and application of innovative science-based technologies to make more efficient use of the world’s water resources.

Our Core Values

Honesty and Integrity… in all relationships

Respect and Trust… everyone’s voice is valuable

Reliability, Dependability and Consistency… we can be counted on.

Over the past 35+ years, Mazzei has developed products to provide solutions to water and wastewater problems in the municipal, industrial and agriculture markets,

  • solutions to disinfection and sanitation problems for all markets including pools/spas and aquatics, and
  • a solution for wine pump-over aeration.

Today Mazzei maintains its focus on research and development and is utilizing in-house computational fluid dynamics software to improve its mixing and contacting technologies, which is evident in Mazzei’s:

  • Pipeline Flash Reactor—rapidly mixing ozone, oxygen or air sidestreams into bulk water flow
  • AirJectionWastewater Aeration System—energy efficient, low cost, quiet solution to wastewater problems with no maximum depth limitations
  • GDT Ozone Contacting System—no other system transfers ozone into solution faster and with a higher mass transfer rate than the GDT
  • AirJection Irrigation System—spoon feeding crops by optimally blending air and water and delivering it directly to the root zone for improved yields and water use and fertilizer efficiencies

These systems integrate the broad line of Mazzei patented products which include Venturi Injectors, specialized Mixing Nozzles and Nozzle Manifolds, Degas Separators, and Flash Mixers. Whatever your operation or application—whether you’re mixing or contacting, aerating or irrigating—Mazzei can deliver a cost-effective solution.
