OxyStar®

Aspirating Aerator


The OxyStar® aspirating aerator is used in municipal and industrial wastewater applications to introduce oxygen into lagoons, equalization basins, aerobic digesters, sludge holding basins, and/or activated sludge systems. The unit provides efficient fine-bubble aeration and thorough circulation and mixing of basin contents. OxyStar aerators are an ideal solution for upgrading, retrofitting, supplementing, or replacing under-performing aeration technologies.



How It Works



OxyStar aspirating aerators mix and oxygenate water by rotating a submerged propeller. As the propeller rotates, it creates a low-pressure zone beneath the surface of the water. The pressure gradient aspirates air through the hollow shaft, discharges it into the water, and the turbulence created by the propeller shears it into fine-bubble aeration.
