A Graphical Representation of Membrane Filtration
SIAM Journal on Applied Mathematics, 2022 We analyze the performance of membrane filters represented by pore networks using two criteria: 1) total volumetric throughput of filtrate over the filter lifetime and 2) accumulated foulant concentration in the filtrate. We first formulate the governing equations of fluid flow on a general network, and we model transport and adsorption of particles ...

Fractional Calculus-based Modelling of Membrane Filtration [PDF]
Kemija u Industriji, 2022 The aim of this work was to model the deep bed and cake filtration process using an alternative approach based on a fractional calculus (FC). The considered experimental data in this study were extracted from published studies. The data used in FC models

Cross-flow microfiltration applied to oenology: A review [PDF]
, 2011 The cross-flow microfiltration applied to wine filtration has become a legitimate alternative to conventional filtration processes. However, membrane fouling which affects the operating costs and the plant maintenance, limits the widespread application ...

Fouling mechanisms in constant flux crossflow ultrafiltration [PDF]
, 2019 Four fouling models due to Hermia (complete pore blocking, intermediate pore blocking, cake filtration and standard pore blocking), have long been used to describe membrane filtration and fouling in constant transmembrane pressure (ΔP) operation of ...
