Biological Oxygen Demand Removal Efficiency
Biological Oxygen Demand (BOD) Removal Efficiency Formula |

\( BOP_{re} \;=\; (BOD_i \; BOD_e \;/\; BOD_i) \; 100 \) (BOD Removal Efficiency) \( BOD_i \;=\; BOD_e \; ( 100 \;/\; 100 - BOD_{re} ) \) \( BOD_e \;=\; BOD_i \; ( \; 1 - (BOP_{re} \;/\; 100) \; ) \) |

| \( BOP_{re} \) = BOD Removal Efficiency | - | \(dimensionless\) |
| \( BOD_i \) = BOD Concentration in the Influent (Incoming Water) | - | \(mg\;/\;L\) |
| \( BOD_e \) = BOD Concentration in the Effluent (Teated Wastewater) | - | \(mg\;/\;L\) |
Biological oxygen demand (BOD) removal efficiency is a parameter used in wastewater treatment to assess the effectiveness of a treatment process in reducing the organic pollutants in water. BOD measures the amount of oxygen required by aerobic microorganisms to break down organic matter in water over a specified period, usually 5 days (\(BOD_5\)).
BOD removal efficiency indicates how well a wastewater treatment system, like a biological treatment plant, is removing organic material from the influent (untreated wastewater). It is typically calculated as a percentage, comparing the BOD levels in the influent (incoming water) to those in the effluent (treated water).
