  • Earthquake Resistant Ductile Iron Pipe, Valve, And Hydrant System
    Earthquake Resistant Ductile Iron Pipe, Valve, And Hydrant System

    Recently, ASCE released its Infrastructure Report Card, giving the nation’s drinking water infrastructure a D: in poor to fair condition and mostly below standard. Many water utilities and communities are doing the hard but necessary thing in finding the resources to upgrade their aging water infrastructure. And, for those in earthquake prone areas, hopefully considering an earthquake resistant system.

  • Municipal Ozone Dissolution Systems: Pipeline Flash Reactors
    Municipal Ozone Dissolution Systems: Pipeline Flash Reactors

    Regulatory pressure, water scarcity and public health concerns have increased the use of ozone as a primary disinfectant and essential oxidant, making ozone a key 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.

  • Pipeline Flash Reactor: Rapid Ozone Mass Transfer In A Small Footprint

  • GDT Degas Gas Separator: High-Performance Gas Separation
    GDT Degas Gas Separator: High-Performance Gas Separation

    The Mazzei GDT™ Degas Separator is a patented unit that utilizes centrifugal force to create a vortex enabling entrained gases to be extracted from water. The water-entrained gas mixture enters the top of the separator tangentially and flows through an accelerator plate, which increases velocity. The water spins down through the separator and exits the bottom. The entrained gas travels through the vortex where it passes into a collector and flows out the top of the separator. The separated gasses exit the separator through a degas relief valve.

  • UV Small Footprint And Flexible Hydraulics Makes Space For The Future
    UV Small Footprint And Flexible Hydraulics Makes Space For The Future

    When a piece of process equipment needs to be replaced, it is tempting to go with a straight replacement in kind – same manufacturer, same model, just the latest version of “the same”. But often, full consideration of other options opens new possibilities for your treatment plant. That was certainly the case for Plainfield, Indiana.
