f m formula Simply put the F M ratio is a measure of the amount of food or BOD that is given to the microorganisms in the aeration tank The microorganisms are the mixed liquor volatile suspended solids or MLVSS Here s the formula to
The Food to Microorganisms Ratio F M ratio is a key parameter used in wastewater treatment processes to assess the organic loading rate and efficiency of the treatment system Food in F M is usually BOD5 in lbs or kg per day The 5 day lag in data can be a problem so many systems use either COD or TOC as a substitute If you want to use either COD or TOC you need to find the average ratio of either to BOD5

MLVSS MLSS x decimal volatile matter VM Key Point The food F value in the F M ratio for computing loading to an activated biosolids process can be either BOD or COD The F M ratio is a process control number that helps you to determine the proper number of microorganisms for your system To do this calculation you will need the following information
The food to microorganism ratio or F M is a measurement of the food entering the activated sludge process and the microorganisms bacteria in the aeration tanks Each activated sludge Once an imbalance in F M is detected see the calculating F M heading below there are at least four ways wastewater operators can adjust this ratio to maintain proper treatment in their
