If the flow to the aeration tank is 3,120,000 gpd, what is the lbs/day BOD loading? 5 NOTE: BOD content of 155 mg/L determined by lab test. This is “Food” in F/M calculation. Answer: 4,033 lbs/day
WebWhen calculating COD, BOD, or SS loading on an aeration process (or any other treatment process),loading on the process is usually calculated as lb/day. The following equation is used: BOD, COD, or SS loading (lb/day) = mg/L x MGD x 8.34 lb/gal Example:- The BOD concentration of the wastewater entering an aerator is 210 mg/L.
