• Class B biosolids
• Odor control
• Elevated digester temperatures

Ovivo’s AirBeam^™ cover brings together Hallsten Aluminum’s experience with extruded aluminum covers and Ovivo’s experience on aerobic digestion to bring you a system that can help meet your biosolids needs. By integrating our single drop diffuser system into the digester cover, Ovivo is able to keep the digester contents at higher temperatures thus improving overall performance. This improved performance allows Ovivo to offer a Class B biosolids guarantee in a smaller footprint than could be achieved in an uncovered digester. The Enviropquip® AirBeam cover also provides owners with integrated odor control by preventing the release of any malodorous compounds.

• Aesthetically pleasing finish
• Lower cost compared to geodesic dome
• No in-basin maintenance
• Minimizes digester tank volumes needed

For those facilities that see cold temperatures in the winter, the Enviropquip^® AirBeam^™ cover is an ideal way to keep the solids in the digester at higher temperatures. This allows owners to have smaller digester tank volumes while still meeting Class B criteria. The AirBeam cover is also easy to install and more affordable than a geodesic dome cover system. Finally, the AirBeam cover offers owners an aesthetically pleasing finish that requires no in-basin maintenance.
