TLDR
Experimental results showed that within nine days the nitrification rate in a biofilm of constant thickness could change by a factor of five, and model predictions indicated that these changes must be due to a significant shift of the biofilm population.About:

Density, porosity, and pore structure of biofilms
Tian C. Zhang,Paul L. Bishop +1 more
TL;DR: The densities, porosities, specific surface area, and mean pore radius of biofilm were determined and are helpful in obtaining a much clearer physical description of biofilms.
Journal ArticleDOI
Simulation of growth and detachment in biofilm systems under defined hydrodynamic conditions
TL;DR: The biofilm thickness during the homogeneous growth phase can be regarded constant throughout the reactor, but was found to be very heterogeneous during the quasi-steady-state and the washout experiments.
Journal ArticleDOI
Influence of detachment mechanisms on competition in biofilms
TL;DR: It is concluded that the application of results from mathematical models assuming a constant biofilm thickness may be misleading when predicting the performance of systems with large fluctuations of the biofilm Thickness over time.

Evaluation of tortuosity factors and effective diffusivities in biofilms
Tian C. Zhang,Paul L. Bishop +1 more
TL;DR: In this article, a cylindrical model and a random porous cluster model were developed to evaluate tortuosities, tortuosity factors, and effective diffusivities within biofilms, based on measurable biofilm properties.

Modeling of biofilm systems: a review.
Harald Horn,Susanne Lackner +1 more
TL;DR: The interaction between the fluid and biofilm structures was addressed more seriously by no longer considering the bio film structures as being rigid, enabling one to describe biofilms as viscoelastic systems that are not only able to grow and produce but also be deformed or even dislodged if external forces are applied.
