Implemented New MBBR System to Reduce BOD by >90% and Meet Permit Requirements  


MBBR System for Paper Mill

Project: bioFASTM MBBR System for Paper Mill

Industry: Pulp & Paper

Application: Biochemical Oxygen Demand (BOD) Removal and Formaldehyde Removal

Application Parameters:

Application Parameters

Problem: The existing rotating biological contactors (RBCs) of the Paper Mill were approaching the end of their service life and presented constant operational issues. Additionally, the RBCs were not completely removing the formaldehyde concentrations in the wastewater.

Solution: After successful planning and design, bioprocessH2O supplied a two-stage bioFAS™ MBBR biological treatment process to reduce BOD and formaldehyde at varying flow and organic loading rates.

Status/Results: The bioFAS™ MBBR System effectively removes BOD by >90%. The new system easily meets the NPDES Discharge Permit Requirements. The system is also able to operate with minimal operator attention and oversight.
