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.
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.
