Retrofit Aeration

The Mazzei AirJection^® Wastewater Aeration retrofit provides supplemental air to aeration basins and other water systems requiring an increase in dissolved oxygen concentrations. An AirJection Wastewater Aeration retrofit package consists of a drop-in aeration manifold with a surface mounted, hydraulically driven Mazzei^® Venturi injector that can be installed in a single day, to any basin depth, without the need to drain the aeration basin or pond.

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

Compared with diffusers and mechanical aerators, Mazzei offers...

• Whisper quiet operation: no blower noise, no splashing
• Non-fouling: no fouling factor in design
• Efficiency (SAE) increases with depth
• High efficiency in high-solids basins
• No volatilization of odor compounds
• Pinpoint aeration and mixing of potential septic zones
• Certified performance
