How to calculate seeded bod
WebTo calculate the pounds of Biochemical Oxygen Demand (BOD) or suspended solids (SS) removed each day, we need to know the mg/L BOD or suspended solids removed and the plant flow, then we can use the mg/L to lb/day formula: BOD removed, lb/day = BOD, mg/L x Flow, MGD x 8.34 lb/gal Example: Web11 apr. 2024 · The ratio of the seed BOD to 300 mL will be used to calculate the seed correction for seeded samples.
