Cell yield (Y) is the amount of new cell mass created per unit of substrate removed. In wastewater, we usually define substrate as BOD5, COD, or TOC. In most cases a true defined substrate is unknown becuase the influent is a mix from multiple streams. So over the years, data has been collected from multiple systems with differing influent makeup, temperatures, F/M ratios, pH, and any number of other environmental factors. I'll distill some of the information below:
Now for a general table of Cell Yield
