The effect of air stripping on a chemostat is Investigated. An operating diagram is constructed to illustrate the relationship between the volatile substrate and the dilution rate subjected to different amounts of air stripping. Air stripping provides another degree of freedom to operate a chemostat in addition to manipulating feed concentration and dilution rate. Thus, a high dose of feed substrate can be tolerated while still maintaining the process in a stable‐operating mode. A stable operation of a chemostat is guaranteed when a proper combination of feed substrate concentration, initial start‐up conditions and aeration rates is implemented.
