WebNitrifying bacteria have a slower growth than the heterotrophic bacteria, which comprises the greater proportion of the biomass in both fixed film and suspended growth systems. The denitrification step is a biological process through which nitrate is converted to nitrogen and other gaseous-end products. Web5 de nov. de 1999 · The on-line estimation of the maximum specific growth rate of autotrophic biomass is addressed in this article. A general nitrification process model, which is valid for any realistic flow pattern, is used to develop the estimation algorithm.
