Population equivalent is used to calculate the quantity of industrial sewage. As it is a tedious process, the industrial sewage (or) waste water is compared with the rate of generation of domestic waste water.

POPULATION EQUIVALENT (STRENGTH OF INDUSTRIAL SEWAGE)

❖ Population equivalent is used to calculate the quantity of industrial sewage. As it is a tedious process, the industrial sewage (or) waste water is compared with the rate of generation of domestic waste water.

❖ This parameter is used to charge the industries for causing pollution (or) discharging waste water against the discharge norms and also to choose appropriate treatment methods.

Strength of Industrial Sewage (BOD5 days) = [Standard BOD5 days of domestic sewage per person per day] x [Population equivalent]

BOD5 of domestic sewage = 0.08 kg/day/person.

e.g.: If BOD5 of industrial sewage = 300 kg/day, then

Population equivalent = 300 / 0.08 = 3750.
