Successful deployment of Tri-Oval Oxidation Ditch system won Technical Merit in Wastewater award
Aeration Industries Intl., Inc. has received an Environmental Business Journal (EBJ) Business Achievement Award in the Technology Merit: Water/Wastewater category for the successful deployment of its Tri-Oval Oxidation Ditch wastewater treatment system.
The Tri-Oval system integrates the company’s Aire-O2 Triton process aerator/mixer into the Oxidation Oval format, providing subsurface horizontal mixing at sufficient velocities to prevent solids from settling. This permits longer entrainment of the unit’s fine bubble diffused air and allows for deeper ditch designs with smaller footprints. The mounting of the Triton units in the ditch is clean and simple, eliminating the need for complex concrete structures and making access for inspection and maintenance very easy.
The subsurface action of the Triton units eliminates the need for covers. And the dual mode functionality of the Triton units allows for unsurpassed process control for BNR treatment without inhibiting mixing, resulting in energy conservation and high effluent quality. Recognition of these advantages in the industry has recently led to the design and construction of three new Tri-Oval oxidation ditches in 2008, with the first placed into service in North Dakota at the end of 2008.
