What is the F/M ratio, and how does it differ from OLR?
derived
The food-to-microorganism ratio expresses feed mass (as COD or VS) per unit of active biomass; OLR is feed per unit of reactor volume per day. A high F/M can overload the methanogens and cause volatile fatty acids to accumulate even when OLR looks acceptable on paper.
