The Tri-Oval® Oxidation Ditch System, named for our Aire-O2 Triton® in an oxidation oval, provides superior wastewater treatment process control and design flexibility of the activated sludge process. We specialize in oxidation ditch retrofits,  providing you with the cost savings benefits of little construction, easy installation, low maintenance, and reliable wastewater treatment. The system’s dual-function Aire-O2 Triton aerators/mixers drive fine bubble aeration and mixing up to 33ft deep (10m) and allow for full Biological Nutrient Removal (BNR). The energy efficient Triton can also operate in as shallow as 4ft (1.2m). Rentals are available to keep your plant compliant in emergency situations or with fluctuating loads throughout the year.
