Food to Microorganism Ratio Solution

STEP 0: Pre-Calculation Summary
Formula Used
Food to microorganism ratio = Daily bod/Total Microbial Mass
FM = BOD/Mt
This formula uses 3 Variables
Variables Used
Food to microorganism ratio - Food to microorganism ratio is actually a measurement of the amount of incoming food divided by the Lbs of Microorganisms in your system.
Daily bod - (Measured in Kilogram) - Daily bod load applied to the aeration system.
Total Microbial Mass - (Measured in Kilogram) - Total microbial mass in the system in grams.
STEP 1: Convert Input(s) to Base Unit
Daily bod: 3 Milligram --> 3E-06 Kilogram (Check conversion here)
Total Microbial Mass: 3 Gram --> 0.003 Kilogram (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
FM = BOD/Mt --> 3E-06/0.003
Evaluating ... ...
FM = 0.001
STEP 3: Convert Result to Output's Unit
0.001 --> No Conversion Required
FINAL ANSWER
0.001 <-- Food to microorganism ratio
(Calculation completed in 00.004 seconds)

20 Food to Microorganism Ratio or F/M Ratio Calculators

Microbial Mass in Aeration System given MLSS
Go Total Microbial Mass = Daily bod/((Sewage Flow*Influent BOD)/(Volume of Tank*MLSS))
BOD Load Applied given MLSS
Go Daily bod = Total Microbial Mass*((Sewage Flow*Influent BOD)/(Volume of Tank*MLSS))
MLSS given BOD Load Applied to Aeration System
Go MLSS = (Total Microbial Mass*Sewage Flow*Influent BOD)/(Volume of Tank*Daily bod)
Volume of Tank given MLSS
Go Volume of Tank = (Total Microbial Mass*Sewage Flow*Influent BOD)/(MLSS*Daily bod)
BOD Influent given MLSS
Go Influent BOD = (Daily bod*MLSS*Volume of Tank)/(Total Microbial Mass*Sewage Flow)
Sewage Flow given MLSS
Go Sewage Flow = (Daily bod*MLSS*Volume of Tank)/(Total Microbial Mass*Influent BOD)
Biological Oxygen Demand influent
Go Biological oxygen demand = (Food to microorganism ratio*Volume of Tank*MLSS)/Sewage Flow
Volume of Tank given Food to Microorganism Ratio
Go Volume of Tank = (Sewage Flow*Influent BOD)/(Food to microorganism ratio*MLSS)
Food to Microorganism Ratio given MLSS
Go Food to microorganism ratio = (Sewage Flow*Influent BOD)/(MLSS*Volume of Tank)
Mixed Liquor Suspended Solid
Go MLSS = (Sewage Flow*Influent BOD)/(Food to microorganism ratio*Volume of Tank)
Sewage Flow given Food to Microorganism Ratio
Go Sewage Flow = (Food to microorganism ratio*Volume of Tank*MLSS)/Influent BOD
Total Microbial Mass given Food to Microorganism Ratio
Go Total Microbial Mass = Daily bod/Food to microorganism ratio
Daily BOD Load given Food to Microorganism Ratio
Go Daily bod = Food to microorganism ratio*Total Microbial Mass
Food to Microorganism Ratio
Go Food to microorganism ratio = Daily bod/Total Microbial Mass
MLSS given Microbial Mass in Aeration System
Go MLSS = (Total Microbial Mass/Volume of Tank)
Volume of Tank given Microbial Mass in Aeration System
Go Volume of Tank = Total Microbial Mass/MLSS
Microbial Mass in Aeration System
Go Total Microbial Mass = MLSS*Volume of Tank
Sewage Flow into Aeration System given BOD Load applied
Go Sewage Flow = Daily bod/Influent BOD
BOD of Influent Sewage given BOD Load applied
Go Influent BOD = Daily bod/Sewage Flow
BOD Load applied to Aeration System
Go Daily bod = Sewage Flow*Influent BOD

Food to Microorganism Ratio Formula

Food to microorganism ratio = Daily bod/Total Microbial Mass
