A simple model describing nitrate and nitrite reduction in fluidized bed biological reactors.

A uniquely simple model is developed to describe the NO(3) (-) and NO(2) (-) concentration profiles within a dentrification fluidized bed biological reactor. This simple model is compared to experimental data, and to a more complex model similar to those previously proposed in the literature. The simple model fits the experimental data at least as well as the more complex model. (c) 1997 John Wiley & Sons, Inc. Biotechnol Bioeng 54: 543-548, 1997.
