Multiple interval methods for ODEs with an optimization constraint
… order ordinary differential equations arising in biofilm modelling. This class of problems is challenging for several reasons. One of the reasons is that the underlying solution has a steep slope, making it difficult to resolve. We propose a new numerical method with techniques such as domain …

Distribution and Characteristics of Biomass in an Upflow Biological Aerated Filter
… differed between fractions and between type of biofilms, with a larger value for detached and detachable fractions and a lower value for a largely heterotrophic biofilm, implying a difference in the composition of the biomass matrix that could be related to the attachment state of the biomass. …

Biostability In Drinking Water Distribution Systems Study At Pilot-scale
… water quality, which was observed in all PDS. Modeling effort demonstrated that HPC levels reached a maximum within five days after water quality change and return to initial level ten days after the change. Since alkalinity was used as a tracer of the steady-state water quality change, time to …

Mathematical Modeling for Nitrogen Removal via a Nitritation: Anaerobic Ammonium Oxidation-Coupled Biofilm in a Hollow Fiber Membrane Bioreactor and a Rotating Biological Contactor
… anaerobic ammonia oxidation (anammox)-coupled biofilm in a counter-diffusion hollow fiber membrane bioreactor (HFMBR) and a nitritation: anammox-coupled biofilm in a co-diffusion rotating biological contactor (RBC) were developed and implemented using AQUASIM. Four different start-up scenarios …
