  1. Pipeline Flash Reactor
    5/23/2017

    Municipal wastewater plants employ multiple treatment methods to increase dissolved oxygen prior to final discharge into receiving waters. Mazzei Injector’s Pipeline Flash Reactor™ provides rapid oxygen transfer within a compact footprint. A small sidestream is passed through a Mazzei injector to draw in ambient air.

    This diagram shows the steps taken at a conventional activated sludge wastewater treatment plant.

  3. Wastewater Airjection Systems

    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.

  4. Airjection Wastewater Aeration System: Do More With Less!

    It should come as no surprise that traditional surface aeration affects only the surface. That allows anaerobic bacteria to proliferate beneath the surface and produce unpleasant odors. Nothing “gets to the bottom” of pond or basin water treatment like the Mazzei AirJection System, which circulates water through the patented, high-efficiency Mazzei® Injectors, delivering dissolved oxygen from the bottom up for complete aeration.

  5. Design Optimization For New And Retrofitted Water And Wastewater Systems

    Predicting the mass transfer and mixing performance of gas-liquid systems is fraught with complexity. Traditional modeling approaches depend on broad assumptions and simplifications which may misrepresent actual flow conditions – this is especially crucial for multiphase flows in retrofit applications in the water/wastewater industry.

  6. Municipal Ozone Dissolution Systems: Sidestream Ozone Injection Skids
    5/23/2017

    Regulatory pressure, water scarcity and public health concerns have increased the use of ozone as a primary disinfectant and essential oxidant, making ozonation a crucial treatment process in municipal water, wastewater and recycling facilities. Mazzei’s ozone dissolution systems are designed to work with a facility’s ozone generators to provide safe and rapid transfer of ozone gas to solution.

  7. Small Water Company Solutions: Taste-Odor Problems?
    5/23/2017

    Water quality issues plague many small water companies in the US. The issues range from oxidation to disinfection to aesthetics, but no problem impacts a system operator more than water that tastes or smells bad. Customer complaints can drive you crazy and cause you to spend your valuable time on the phone. There is a good solution: The Mazzei Ozone Contacting System.

  8. Thermal Flow Meters For Mixed Gas Applications
    5/22/2017

    Fox Thermal Flow Meters use a constant temperature differential (constant Δ T) technology to measure mass flow rate of air and gases.

  9. When Improving America’s Infrastructure, Don’t Forget Forests
    5/19/2017

    America’s water infrastructure is in a state of disrepair, as evidenced by disasters such as the public health crisis in Flint, Michigan and dangerous flooding at the Oroville Dam.

  10. Ozone Water Treatment Systems
    5/19/2017

    Mazzei has been developing ozone transfer systems for the industrial and municipal water industries for more than two decades. From rural water purveyors treating a few gallons per minute to large municipal plants treating millions of gallons per day, Mazzei provides proven, cost-effective solutions.
