Population Equivalent in Wastewater Treatment

Population equivalent is a term used to describe the amount of organic pollutants released by a population that a wastewater treatment plant can handle. It is a measure of the loading capacity of a treatment plant and is expressed in terms of the number of people whose wastewater the plant can treat. The following is the correct expression of population equivalent:

BOD of industrial sewage kg/day / 0.08 kg/person/day

Explanation:

BOD of industrial sewage: The amount of BOD (Biochemical Oxygen Demand) in the industrial sewage is measured in kg/day.

0.08 kg/person/day: The average BOD generated per person per day is assumed to be 0.08 kg/person/day.

Dividing the total BOD by the average BOD generated per person per day gives the number of people whose wastewater the treatment plant can handle. This is expressed as population equivalent.

Therefore, the correct expression of population equivalent is BOD of industrial sewage kg/day / 0.08 kg/person/day.
