In which one of the following the BOD (Biochemical Oxygen Demand) of sewage (S), distillery effluent (DE), paper mill effluent (PE) and sugar mill effluent (SE) have been arranged in ascending order ?

A

`SE lt S lt PE lt DE`

B

`SE lt PE lt S lt DE`

C

`PE lt S lt SE lt DE`

D

`S lt DE lt PE lt SE`

Text Solution

Verified by Experts

The correct Answer is:
C
Usually, BOD of PE =30 mg/lit., S=300-400 mg/hit, SE=2000-3500 mg/lit, and DE=3400 mg/lit. Therefore `PE lt S lt SE lt DE`
