For typical domestic sewage at 20°C, what is the approximate value of the rate constant (k) in the BOD reaction?
Understand the Problem
The question asks for the approximate rate constant (k) in the BOD (Biochemical Oxygen Demand) reaction for typical domestic sewage at 20°C. This requires knowledge of environmental engineering principles related to water quality and wastewater treatment.
Answer
The rate constant (k) is approximately 0.23 per day.
The approximate value of the rate constant (k) in the BOD reaction for typical domestic sewage at 20°C is 0.23 per day.
Answer for screen readers
The approximate value of the rate constant (k) in the BOD reaction for typical domestic sewage at 20°C is 0.23 per day.
More Information
The rate constant (k) in the BOD reaction is influenced by the characteristics of the wastewater, including the type and concentration of organic matter, the presence of microorganisms, and the temperature. A higher k value indicates a faster rate of biodegradation.
Tips
The value of k can vary depending on the specific characteristics of the sewage, so it's important to use a value that is appropriate for the specific situation.
