Bod loading calculation
WebThe loading rate of aeration tank is based on the following four parameters: 1. Hydraulic Retention Time (HRT) 2. Volumetric BOD Loading or Volumetric Organic Loading 3. Food to Micro-Organism Ratio (F/M Ratio) 4. Mean Cell Residence Time (MCRT) or Sludge Retention Time (SRT) or Sludge Age. Parameter # 1. Hydraulic Retention Time (HRT): WebThe biochemical oxygen demand, or BOD, is the amount of organic matter which can be biologically oxidized in 5 days at 20°C in the dark. This is a way of measuring how much organic matter is in the water. The …
