THE ORBAL® SYSTEM FOR SIMULTANEOUS NITRIFICATION – DENITRIFICATION
TrueSND™ Biological Treatment
Easily identified by its concentric loop design, the Orbal® system, part of the Envirex® product family, uses an activated sludge process designed to address today’s nutrient and Stormflow issues.
The simultaneous nitrification/denitrification (SND) process is the backbone. The Orbal system features dedicated zones for specific treatment purposes. These treatment zones operate in series during the SND treatment process. The Orbal system has been on the leading edge of SND plant designs for more than 50 years.
