To quickly estimate key design parameters for a based on input parameters like population, flow, and BOD load.
Sized based on the Surface Overflow Rate (SOR) , often ranging from 15 to 30 for average flow. stp design calculation
$$PHF = ADF \times PF$$
Volume (m³) = (BOD load × SRT) / (MLSS × F/M ratio) Where: - SRT = Sludge Retention Time (days) → 10–20 days - MLSS = Mixed Liquor Suspended Solids (mg/L) → 3000–4000 - F/M = Food to Mass ratio → 0.1–0.3 kg BOD/kg MLSS/day To quickly estimate key design parameters for a
