"WebA unique feature of a biological CSTR is the washout point. When the flow rate is increased so that the microbes can no longer reproduce fast enough to maintain a population, the microbes wash out of the tank, and the reaction ceases. This washout point represents the limits of maximum flow rate for operation. IV.D.2 Classification " - Cstr washout curve

WebWashout of the microbes must absolutely be avoided, therefore the HRT must not be below 10 days (Eder, 2006). The HRT is calculated from [8.2]HRTdays=Netdigestervolumem3Substrateinputm3/day Both the OLR and the HRT make reference to the effective digester volume, which is the volume actually available to … WebConcentration curves at different Peclét numbers The CSTR-in-series model considers a sequence of completely mixed tanks as a fit to sequential zones of the non-ideal reactor. In a sense, this is similar to considering the PFR as a sequence of non-interacting differential volumes. Thus, both the E and F curves will be the sum of a series: 1 / E
