Here is how the Percent Stabilization equation looks like.

10.4268 = (\frac{164 - 4.9 - 1.42 \cdot 100}{164}) \cdot 100

10.4268 = (\frac{164kg/d - 4.9kg/d - 1.42 \cdot 100kg/d}{164kg/d}) \cdot 100

10.4268 = (\frac{164 - 4.9 - 1.42 \cdot 100}{164}) \cdot 100

Percent Stabilization Solution

Follow our step by step solution on how to calculate Percent Stabilization?

FIRST Step Consider the formula

%S = (\frac{BOD in - BOD out - 1.42 \cdot P x}{BOD in}) \cdot 100

Next Step Substitute values of Variables

∴

%S = (\frac{164kg/d - 4.9kg/d - 1.42 \cdot 100kg/d}{164kg/d}) \cdot 100

Next Step Convert Units

∴

%S = (\frac{0.0019kg/s - 5.7E-5kg/s - 1.42 \cdot 0.0012kg/s}{0.0019kg/s}) \cdot 100

Next Step Prepare to Evaluate

∴

%S = (\frac{0.0019 - 5.7E-5 - 1.42 \cdot 0.0012}{0.0019}) \cdot 100

Next Step Evaluate

∴

%S = 10.4268292682926

LAST Step Rounding Answer

∴

%S = 10.4268

Percent Stabilization Formula Elements

Variables

Percent Stabilization

Percent Stabilization is defined as percentage of bod removal.

Symbol: %S

Measurement: NAUnit: Unitless

Note: Value should be greater than 0.

Formulas to find Percent Stabilization

BOD In

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.

Symbol: BOD_in

Measurement: Mass Flow RateUnit: kg/d

Note: Value should be greater than 0.

Formulas to find BOD In

BOD Out

BOD Out referred as the amount of dissolved oxygen exits anaerobic digester.

Symbol: BOD_out

Measurement: Mass Flow RateUnit: kg/d

Note: Value should be greater than 0.

Formulas to find BOD Out

Volatile Solids Produced

Volatile Solids Produced refers to the organic fraction of the total solids present in the sludge.

Symbol: P_x

Measurement: Mass Flow RateUnit: kg/d

Note: Value should be greater than 0.

How to Evaluate Percent Stabilization?

Percent Stabilization evaluator uses Percent Stabilization = ((BOD In-BOD Out-1.42*Volatile Solids Produced)/BOD In)*100 to evaluate 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 evaluate Percent Stabilization using this online evaluator? To use this online evaluator for Percent Stabilization, enter BOD In (BOD_in), BOD Out (BOD_out) & Volatile Solids Produced (P_x) and hit the calculate button.

FAQs on Percent Stabilization

What is the formula to find Percent Stabilization?

The formula of Percent Stabilization is expressed as Percent Stabilization = ((BOD In-BOD Out-1.42*Volatile Solids Produced)/BOD In)*100. Here is an example- 10.36585 = ((0.00189814814814815-5.6712962962963E-05-1.42*0.00115740740740741)/0.00189814814814815)*100.

How to calculate Percent Stabilization?

With BOD In (BOD_in), BOD Out (BOD_out) & Volatile Solids Produced (P_x) we can find Percent Stabilization using the formula - Percent Stabilization = ((BOD In-BOD Out-1.42*Volatile Solids Produced)/BOD In)*100.
