Project: bioFAS™ MBBR System for Rendering Facility

Industry: Food & Beverage

Application:

  • Biochemical Oxygen Demand (BOD) Removal
  • Nitrification of Ammonia

Application Parameters:

Rendering Design Criteria Table.jpg

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.
