Surface aerators are a practical, proven solution for oxygen transfer and mixing in wastewater treatment basins, equalization tanks, and lagoons. By drawing air at the water surface and dispersing it into the liquid while creating strong circulation, surface aerators help maintain stable dissolved oxygen (DO) levels and prevent solids from settling.
At PMC Engineering, we supply surface aerators designed for continuous industrial operation, with robust mechanical construction, easy maintenance access, and options suitable for both municipal and industrial wastewater applications. Whether your priority is process stability, energy efficiency, or simple installation, our surface aerator range provides a reliable aeration method with straightforward mechanical design.
Where Surface Aerators Fit Best
Surface aerators are commonly selected when you need:
-
Effective mixing + aeration with a single machine
-
A compact solution for existing concrete basins (retrofits)
-
Aeration for lagoons / open tanks where diffuser systems may be difficult
-
Quick installation with minimal pipework
