Retrofit System to Reduce BOD >75%

Project: bioFAS MBBR for Pulp & Paper Production Facility, Ox Industries

Industry: Pulp & Paper

Application:

• Biochemical Oxygen Demand (BOD)

Application Parameters:

Problem: Ox Paperboard LLC located in Halltown, West Virginia needed to upgrade its wastewater treatment process because the BOD load produced by the paper mill exceeded the treatment capacity of the existing SBR.

Solution: bioprocessH2o retrofitted an existing clarified water tank into a single-stage MBBR system to reduce the BOD load to the existing SBR. The treated wastewater from the bioFAS MBBR is discharged to the existing SBR for BOD polishing and solids removal to meet the effluent requirements.

Status/Results: The bioFAS MBBR system reduces carbonaceous BOD by >75%, allowing existing SBR to meet the effluent BOD limit.
