WebWhat is the ultimate carbonaceous BOD (Lo)? c. What would be the remaining oxygen demand after five days? a. BOD5 = (DOi –DOf)/P = (9.0 mg/L – 3.0 mg/L) 0.030 BOD5 = 200 mg/L b. BOD5 = Lo(1-e-kt) Lo= BOD5/ (1-e-kt) Lo= (200 mg/L)/ (1-e-0.22 (5)) Lo = 300 mg/L c. (300 mg/L – 200 mg/L) = 100 mg/L remaining oxygen demand WebTranscribed image text: Suppose some wastewater has a BOD5 equal to 180mg/L and a reaction rate k equal to 0.22 /day.

Another reason to take it as standard is to avoid the interference of nitrification of bacteria as this starts after 6th or 7th day. Therefore, by avoiding nitrification we get only “CARBONACEOUS BOD”. kurt wacker columbus ohWebJun 7, 2024 · The BOD 5 is valuable as an indicator of the pollutional strength of effluents from aquaculture farms. Typical BOD 5 concentrations in aquaculture effluents are between 5 and 30 mg per liter, but both lower and higher concentrations may occur. The BOD 5 is not especially useful as an indicator of oxygen demand within culture systems. margaux early childhood school
