Wastewater Biochemical Oxygen Demand (BOD) Reduction

Biochemical Oxygen Demand (BOD) Reduction

The MBBR process is ideally suited for carbonaceous biochemical oxygen demand and chemical oxygen demand (BOD/COD) removal applications.

MBBR processes retain a large volume of biofilm within the biological wastewater treatment process. As a result, degradation of biodegradable contaminants are sustained in highly compact tank sizes. Without the requirement to return sludge, the process provides increased protection against toxic shock, while automatically adjusting to load fluctuations.

Benefits for Biochemical Oxygen Demand (BOD) Reduction include:

• High Land-Use Efficiency
• Unattended operation
• Expandable by simple addition of biofilm carriers and air by volume

Typical applications include:

• Industrial wastewater treatment to reduce BOD to below 250 mg/L
• Groundwater treatment to reduce phenol levels to less than 1 mg/L
• Municipal wastewater treatment to achieve < 10 mg/L of BOD
• Lagoon elimination
