Some wastewater has a BOD5 of 150 mg/L at 20° C. The reaction rate k at that temperature has been determined to be 0.20/day. Find BOD5 (in mg/L) at 15° C.
Answers: 2
= Biochemical oxygen demand at t days
= the ultimate carbonaceous
= rate of the reaction constant at various temperature (T) = 15
= rate of the reaction constant at standard laboratory = 0.20
= constant = 1.047
