This formula uses 4 Variables

Variables Used

Percent Stabilization - Percent Stabilization is defined as percentage of bod removal.
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.

STEP 1: Convert Input(s) to Base Unit

Endogenous Coefficient given Quantity of Volatile Solids

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

Mean Cell Residence Time given Quantity of Volatile Solids

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

Yield Coefficient given Quantity of Volatile Solids

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

Quantity of Volatile Solids Produced Each Day

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

BOD Out given Quantity of Volatile Solids

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

BOD in given Quantity of Volatile Solids

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

Volatile Solids produced given Percent Stabilization

Go Volatile Solids Produced = (1/1.42)*(BOD In-BOD Out-((Percent Stabilization*BOD In)/100))

BOD Out given Percent Stabilization

Go BOD Out = (BOD In*100-142*Volatile Solids Produced-Percent Stabilization*BOD In)/100

Percent Stabilization

Go Percent Stabilization = ((BOD In-BOD Out-1.42*Volatile Solids Produced)/BOD In)*100

BOD in given Percent Stabilization

Volatile Solids produced given Volume of Methane Gas produced

Go Volatile Solids Produced = (1/1.42)*(BOD In-BOD Out-(Volume of Methane/5.62))

BOD Out given Volume of Methane Gas Produced

Go BOD Out = (BOD In-(Volume of Methane/5.62)-(1.42*Volatile Solids Produced))

BOD in given Volume of Methane Gas Produced

Go BOD In = (Volume of Methane/5.62)+BOD Out+(1.42*Volatile Solids Produced)

Volume of Methane Gas Produced at Standard Conditions

Go Volume of Methane = 5.62*(BOD In-BOD Out-1.42*Volatile Solids Produced)

Hydraulic Retention Time given Volume Required for Anaerobic Digester

Go Hydraulic Retention Time in Seconds = (Volume/Influent Sludge Flow Rate)

Influent Sludge Flow Rate given Volume Required for Anaerobic Digester

Go Influent Sludge Flow Rate = (Volume/Hydraulic Retention Time)

What is BOD?

Biochemical Oxygen Demand is the amount of dissolved oxygen needed by aerobic biological organisms to break down organic material present in a given water sample at certain temperature over a specific time period.

How to Calculate Percent Stabilization?

Percent Stabilization calculator uses Percent Stabilization = ((BOD In-BOD Out-1.42*Volatile Solids Produced)/BOD In)*100 to calculate the Percent Stabilization, The Percent Stabilization formula is defined as a measure used in wastewater treatment to evaluate the extent to which organic matter in sludge has been reduced or stabilized during treatment processes such as anaerobic digestion or composting. It reflects the degree of decomposition of the organic material in the sludge, indicating how much of the initial organic matter has been converted into more stable forms. Percent Stabilization is denoted by %S symbol.

How to calculate Percent Stabilization using this online calculator? To use this online calculator for Percent Stabilization, enter BOD In (BOD_in), BOD Out (BOD_out) & Volatile Solids Produced (P_x) and hit the calculate button. Here is how the Percent Stabilization calculation can be explained with given input values -> 10.36585 = ((0.00189814814814815-5.6712962962963E-05-1.42*0.00115740740740741)/0.00189814814814815)*100.

What is Percent Stabilization?

The Percent Stabilization formula is defined as a measure used in wastewater treatment to evaluate the extent to which organic matter in sludge has been reduced or stabilized during treatment processes such as anaerobic digestion or composting. It reflects the degree of decomposition of the organic material in the sludge, indicating how much of the initial organic matter has been converted into more stable forms and is represented as %S = ((BOD_in-BOD_out-1.42*P_x)/BOD_in)*100 or Percent Stabilization = ((BOD In-BOD Out-1.42*Volatile Solids Produced)/BOD In)*100. 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 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.
