BOD of Influent Sewage given BOD Load applied Solution

STEP 0: Pre-Calculation Summary

Formula Used

Influent BOD = Daily bod/Sewage Flow
Q_i = BOD/Q
This formula uses 3 Variables

Variables Used

Influent BOD - (Measured in Kilogram per Cubic Meter) - Influent BOD is the total amount of BOD which is present in the incoming sewage.
Daily bod - (Measured in Kilogram) - Daily bod load applied to the aeration system.
Sewage Flow - (Measured in Cubic Meter) - Sewage flow into the aeration tank is the sewage flow into the aeration tank when we have prior information of other parameters used.

STEP 1: Convert Input(s) to Base Unit

Daily bod: 3 Milligram --> 3E-06 Kilogram (Check conversion here)
Sewage Flow: 20 Cubic Meter --> 20 Cubic Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q_i = BOD/Q --> 3E-06/20

Evaluating ... ...

Q_i = 1.5E-07

STEP 3: Convert Result to Output's Unit

1.5E-07 Kilogram per Cubic Meter -->0.00015 Milligram per Liter (Check conversion here)

FINAL ANSWER

0.00015 Milligram per Liter <-- Influent BOD

(Calculation completed in 00.004 seconds)
