MBBR to Retrofit Existing RBC and Reduce Ammonia More Than 90%
DarlinG Ingredients - Tennessee
Project: bioFAS™ MBBR System for Rendering Facility
Industry: Food & Beverage
- Biochemical Oxygen Demand (BOD) Removal
- Nitrification of Ammonia
Problem: The Rendering Facility had experienced a failure of a Rotating Biological Contactor (RBC) system and as a result, the existing treatment lagoons were unable to reduce total nitrogen concentrations to meet the Discharge Permit Limits.
Solution: bioprocessH2O was selected to provide a bioFAS™ Moving Bed Biofilm Reactor (MBBR) System equipment package to retrofit and upgrade the existing RBC basins into a two-stage bioFAS™ MBBR process for the reduction of BOD and nitrification of ammonia. Nitrate is returned to the lagoons for denitrification (nitrogen removal).
Status/Results: The bioFAS™ MBBR system effectively reduces BOD and nitrifies ammonia and exceeds the effluent discharge criteria.
