Theoretic similitude of the aerobic biological growth kinetics for the stabilization of organic matter in wastewaters treatment

Abstract

To achieve the stabilization of organic matter in wastewaters treatment, it is not only significant to establish the microbial growth kinetics, but also the interrelation of the removal of nutrients such as nitrogen, given the similitude of coefficients, specific growth rate and the adjustments for water temperature, which represents it for both the removal of organic matter as well as for the nitrification and denitrification processes present in the biological wastewaters treatment. Therefore, this theoretic similitude between microbial growth kinetics and nitrogen removal processes constitutes concise considerations for the dimensioning process of wastewater biological treatment systems, which contribute in the understanding of the simultaneous process of removing organic matter and nutrients from raw wastewater.
