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.
