Question
AWWTP effluent of 0.011 m^3 /s and
a BOD5 of 590 mg/L discharges into
a river. The river has flow of 1.7 m^3
Is., the BOD5 of the river is 0.6 mg/L.
The BOD rate constants (k1) are 0.115
day^-1 for the waste water and 3.7
day^-1 for the river. Calculate the
initial ultimate BOD (Lo) after mixing.
z 9.270 mg/I
z 6.452 mg/I
- 8.233 mg/l
= 7.345 mg/I
