Title Efficient Calculation and Analysis of Steady State Solutions for a Mathematical Model of Nitrifying Bacteria in a Moving Bed Biofilm Reactor
Author(s) Masic, Alma ; Overgaard, Niels ; Heyden, Anders

English abstract
We consider a mathematical model for the nitrification of municipal waste water in a moving bed biofilm reactor. The model consists of two interacting parts. The first part is an essentially one-dimensional mixed-culture biofilm model, based on the classical differential equation paradigm introduced by Wanner and Gujer (Biotech. Bioeng. 28, 1986). This part models nutrient transport, growth and internal composition of the bacterial film located on the inside of the individual AnoxKaldnes-carrier chips in the reactor. The second part of the model describes the nutrient concentrations in the reactor tank. Here we use the standard differential equations for a completely mixed (continuously stirred) reactor. The interaction between the two parts of the system is comprised in the boundary conditions, i.e. the nutrient concentrations at the biofilm-water interface.
