Wastewater Retrofit Aeration

Wastewater Aeration Retrofit

For wastewater facilities requiring increased dissolved oxygen concentrations, the Mazzei AirJection® Wastewater Aeration system with a drop-in MTM nozzle manifold and surface Mazzei Venturi injector(s) is the solution.  The MTM nozzle manifold can be installed at any basin depth without having to drain the aeration basin or pond.  The AirJection Wastewater Aeration system circulates water through the patented, high efficient Mazzei Venturi injector(s), delivering dissolved oxygen from the bottom up for complete aeration; and as basin depths increase, there is more oxygen transferred per horsepower than with the use of other aeration techniques.  

Why Retrofit?

  • Extend hydraulic throughput of an existing aeration basin
  • Supplemental air for peak BOD loading conditions
  • Supplemental air and mixing for stagnant basin zones
