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 … WebJan 1, 1975 · Due to the autocatalytic nature of the system, operating conditions can be encountered for which growth cannot be sustained (the so-called “washout”). A critical value of parameters to avoid this condition is obtained through inspection of the analytical solution of the linearized equations. References (8) D. Herbert et al. J. Gen. Microbiol.
