Product Specification Sheet The ATLAS - DBBR™ (Internal Decanted Bio Balanced Reactor) system integrates conventional decanted reactor technology with EDI’s “equilibrium” solids management program to improve the performance capabilities of lagoon-based wastewater treatment systems. Conventional lagoon treatment systems that are experiencing any of the following conditions will benefit from the application of the ATLAS DBBR system: • Hydraulic or organic overload • Inadequate BOD or TSS reduction • Poor ammonia conversion • High effluent total nitrogen • Reduced cold weather performance...
