Abstract
We investigate point-of-use ceramic water filters by reformulating an existing multi-scale biofilm model that has been developed for porous medium applications. The reactor model is described by a stiff system of quasilinear hyperbolic balance laws, which are studied numerically. The model considers processes related to hydrodynamics and transport of a single target contaminant, growth/death of bacteria (both attached biomass inside the filter base, in the form of biofilms, and suspended bacteria), and mass exchange between the biofilm and suspended bacteria via attachment and detachment. With this model, we investigate the influence of water height and refill frequency on the amount and quality of recoverable water.
