Approximately how many pounds of BOD does each person contribute to the wastewater system daily?

0.10 lbs
0.15 lbs
0.17 lbs
0.20 lbs

The correct answer is: 0.17 lbs

Each person typically contributes around 0.17 pounds of Biochemical Oxygen Demand (BOD) to the wastewater system daily. BOD is a critical measurement in wastewater treatment, reflecting the organic matter present in the water that can deplete oxygen levels when decomposed by microorganisms. Understanding this value helps in sizing treatment facilities and ensuring proper treatment processes are in place to handle the organic load effectively. The other values, while close, do not accurately represent the average contribution for a typical individual per day. Using the approximately 0.17 pounds figure allows for accurate planning and management of wastewater treatment systems, ensuring they can adequately handle the organic load generated by the population served.
