A treatment plant uses chlorination for disinfection of their wastewater. Based on the following chart of chlorine use in lbs, what is the average chlorine dose?

To determine the average chlorine dose for the treatment plant using chlorination for disinfection of wastewater, you will need to calculate the mean of the chlorine use over a certain period, which is typically derived from a dataset showing the amount of chlorine used at different times or conditions.

The average is found by summing all the chlorine amounts used during the specified period and then dividing that total by the number of measurements taken. If the average calculated from the provided dataset equals 67 lbs, this value represents the typical or expected chlorine dose utilized for disinfection purposes in the treatment process.

Chlorination is a common method used in wastewater treatment as it effectively targets pathogenic microorganisms. Understanding the average chlorine dose helps in optimizing the disinfection process, ensuring compliance with health and environmental regulations, while also preventing excess chlorine that could lead to harmful byproducts. For this reason, arriving at an accurate measurement is crucial for both operational efficiency and safety.
