BOD in given Percent Stabilization Solution

STEP 0: Pre-Calculation Summary

Formula Used

BOD In = (BOD Out*100+142*Volatile Solids Produced)/(100-Percent Stabilization)
BOD_in = (BOD_out*100+142*P_x)/(100-%S)
This formula uses 4 Variables

Variables Used

BOD In - (Measured in Kilogram per Second) - BOD In in anaerobic digester design lies in its role as an indicator of the organic load present in the feedstock. High BOD levels suggest a greater concentration of organic matter.
BOD Out - (Measured in Kilogram per Second) - BOD Out referred as the amount of dissolved oxygen exits anaerobic digester.
Volatile Solids Produced - (Measured in Kilogram per Second) - Volatile Solids Produced refers to the organic fraction of the total solids present in the sludge.
Percent Stabilization - Percent Stabilization is defined as percentage of bod removal.

STEP 1: Convert Input(s) to Base Unit

BOD Out: 4.9 Kilogram per Day --> 5.6712962962963E-05 Kilogram per Second (Check conversion here)
Volatile Solids Produced: 100 Kilogram per Day --> 0.00115740740740741 Kilogram per Second (Check conversion here)
Percent Stabilization: 10.36 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

BOD_in = (BOD_out*100+142*P_x)/(100-%S) --> (5.6712962962963E-05*100+142*0.00115740740740741)/(100-10.36)

Evaluating ... ...

BOD_in = 0.00189673302262549

STEP 3: Convert Result to Output's Unit

0.00189673302262549 Kilogram per Second -->163.877733154842 Kilogram per Day (Check conversion here)

FINAL ANSWER

163.877733154842 ≈ 163.8777 Kilogram per Day <-- BOD In

What is BOD?

BOD also called biochemical oxygen demand refers to the amount of oxygen that would be consumed if all the organic materials in a one liter water sample were Oxidised by bacteria and protozoa.

How to Calculate BOD in given Percent Stabilization?

BOD in given Percent Stabilization calculator uses BOD In = (BOD Out*100+142*Volatile Solids Produced)/(100-Percent Stabilization) to calculate the BOD In, The BOD in given Percent Stabilization formula is defined as the critical parameter used to gauge the amount of organic matter in water, which indicates the level of pollution. It measures the amount of dissolved oxygen required by aerobic microorganisms to decompose the organic material present in a water sample over a specified period, typically five days at 20°C. BOD In is denoted by BOD_in symbol.

FAQ

What is BOD in given Percent Stabilization?

The BOD in given Percent Stabilization formula is defined as the critical parameter used to gauge the amount of organic matter in water, which indicates the level of pollution. It measures the amount of dissolved oxygen required by aerobic microorganisms to decompose the organic material present in a water sample over a specified period, typically five days at 20°C and is represented as BOD_in = (BOD_out*100+142*P_x)/(100-%S) or BOD In = (BOD Out*100+142*Volatile Solids Produced)/(100-Percent Stabilization). BOD Out referred as the amount of dissolved oxygen exits anaerobic digester, Volatile Solids Produced refers to the organic fraction of the total solids present in the sludge & Percent Stabilization is defined as percentage of bod removal.

How to calculate BOD in given Percent Stabilization?

The BOD in given Percent Stabilization formula is defined as the critical parameter used to gauge the amount of organic matter in water, which indicates the level of pollution. It measures the amount of dissolved oxygen required by aerobic microorganisms to decompose the organic material present in a water sample over a specified period, typically five days at 20°C is calculated using BOD In = (BOD Out*100+142*Volatile Solids Produced)/(100-Percent Stabilization). To calculate BOD in given Percent Stabilization, you need BOD Out (BOD_out), Volatile Solids Produced (P_x) & Percent Stabilization (%S). With our tool, you need to enter the respective value for BOD Out, Volatile Solids Produced & Percent Stabilization 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?

In this formula, BOD In uses BOD Out, Volatile Solids Produced & Percent Stabilization. We can use 2 other way(s) to calculate the same, which is/are as follows -

BOD In = (Volatile Solids Produced/Yield Coefficient)*(1-Endogenous Coefficient*Mean Cell Residence Time)+BOD Out
