Mazzei, a leader in the design and manufacture of fluid mixing and contacting technologies, provides systems and components for ozone, aeration and chemical treatment for the industrial and municipal water and wastewater sectors. Aeration and ozonation are complicated procedures, but Mazzei patented technologies make these processes easier, more efficient, less expensive and more reliable. Multiphase flow modeling is used to design, analyze and optimize Mazzei individual products as well as multi-component contacting systems. Turn-key systems are available in compact designs. Whatever you need… Mazzei has a solution to your water and wastewater problems. Mazzei began in 1978 with its patented venturi injectors for the agricultural market and continues to provide solutions for irrigation problems today. In addition to chemigation and fertigation, Mazzei has developed technology to help with crop yield and soil health—AirJection irrigation. It optimally blends air and water in drip line systems to deliver the right mixture to the root zone… preventing the soil from becoming anaerobic which would inhibit growth and yield. For wine fermentation, Mazzei has a wine pump-over injector for macro aeration. Wine is pumped through the injector which draws in and uniformly distributes oxygen into the juice improving the fermentation process. The oxygen dose can be honed with a metering value and flowmeter so that it can be monitored and controlled. 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. Whatever your operation or application—whether you’re mixing or contacting, aerating or irrigating—Mazzei can deliver a cost-effective solution.
