BOD in Sewage Solution

STEP 0: Pre-Calculation Summary

Formula Used

BOD = DO Consumed*(Volume of Diluted Sample/Volume of Undiluted Sample)
BOD = DO*(V/V_u)
This formula uses 4 Variables

Variables Used

BOD - (Measured in Kilogram per Cubic Meter) - BOD is the biochemical oxygen demand of waste water.
DO Consumed - (Measured in Kilogram per Cubic Meter) - DO consumed is the total amount of dissolved oxygen consumed.
Volume of Diluted Sample - (Measured in Cubic Meter) - Volume of Diluted Sample is the total space occupied by the diluted sample.
Volume of Undiluted Sample - (Measured in Cubic Meter) - Volume of undiluted sample is the total space occupied by the undiluted sample.

STEP 1: Convert Input(s) to Base Unit

DO Consumed: 12.5 Milligram per Liter --> 0.0125 Kilogram per Cubic Meter (Check conversion here)
Volume of Diluted Sample: 3.5 Cubic Meter --> 3.5 Cubic Meter No Conversion Required
Volume of Undiluted Sample: 2.2 Cubic Meter --> 2.2 Cubic Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

BOD = DO*(V/V_u) --> 0.0125*(3.5/2.2)

Evaluating ... ...

BOD = 0.0198863636363636

STEP 3: Convert Result to Output's Unit

0.0198863636363636 Kilogram per Cubic Meter -->19.8863636363636 Milligram per Liter (Check conversion here)

FINAL ANSWER

19.8863636363636 ≈ 19.88636 Milligram per Liter <-- BOD

BOD in Sewage

Go BOD = DO Consumed*(Volume of Diluted Sample/Volume of Undiluted Sample)

BOD of Industry given Population Equivalent

Go BOD of Industrial Sewage = 0.08*Population Equivalent

BOD given Dilution Factor

Go BOD = DO Consumed*(300/4)

BOD in Sewage Formula

BOD = DO Consumed*(Volume of Diluted Sample/Volume of Undiluted Sample)
BOD = DO*(V/V_u)

What is the Maximum Permissible Limits of BOD?

Maximum allowable concentration for direct environmental wastewater discharge fall around 10 mg/L BOD and maximum allowable concentrations for discharge to sewer systems around 300 mg/L BOD.

How to Calculate BOD in Sewage?

BOD in Sewage calculator uses BOD = DO Consumed*(Volume of Diluted Sample/Volume of Undiluted Sample) to calculate the BOD, The BOD in sewage is defined as the measure of the amount of oxygen required to remove waste organic matter from water in the process of decomposition by aerobic bacteria. BOD is denoted by BOD symbol.

How to calculate BOD in Sewage using this online calculator? To use this online calculator for BOD in Sewage, enter DO Consumed (DO), Volume of Diluted Sample (V) & Volume of Undiluted Sample (V_u) and hit the calculate button. Here is how the BOD in Sewage calculation can be explained with given input values -> 19886.36 = 0.0125*(3.5/2.2).

FAQ

What is BOD in Sewage?

The BOD in sewage is defined as the measure of the amount of oxygen required to remove waste organic matter from water in the process of decomposition by aerobic bacteria and is represented as BOD = DO*(V/V_u) or BOD = DO Consumed*(Volume of Diluted Sample/Volume of Undiluted Sample). DO consumed is the total amount of dissolved oxygen consumed, Volume of Diluted Sample is the total space occupied by the diluted sample & Volume of undiluted sample is the total space occupied by the undiluted sample.

How to calculate BOD in Sewage?

The BOD in sewage is defined as the measure of the amount of oxygen required to remove waste organic matter from water in the process of decomposition by aerobic bacteria is calculated using BOD = DO Consumed*(Volume of Diluted Sample/Volume of Undiluted Sample). To calculate BOD in Sewage, you need DO Consumed (DO), Volume of Diluted Sample (V) & Volume of Undiluted Sample (V_u). With our tool, you need to enter the respective value for DO Consumed, Volume of Diluted Sample & Volume of Undiluted Sample and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.

How many ways are there to calculate BOD?

In this formula, BOD uses DO Consumed, Volume of Diluted Sample & Volume of Undiluted Sample. We can use 1 other way(s) to calculate the same, which is/are as follows -

BOD = DO Consumed*(300/4)
