Aire-O2 Triton TR Series Aerator and Mixer, biological nutrient removal (BNR) is now easier and more cost effective by combining mixing, aeration, and BNR in a single compact unit with separate on/off modes. The Triton’s proprietary engineered propeller/diffuser results in higher oxygen transfer and greater mixing capabilities up to 33 feet (10 meters) deep. You can simply add the Triton to supplement aeration in your current system, without making any changes to infrastructure; making installation easy and reducing costs.
