Modelling of filtration: from the polarised layer to deposit formation and compaction

Patrice Bacchin
Martine Meireles

Résumé

A theoretical study is developed for the modelling of mass accumulation from the polarised layer to the formation of a deposit. Concentrated suspension properties are accounted for through a solid pressure corresponding to osmotic pressure in the suspension and to compression resistance in the deposit. Mass and solvent transfer are depicted through balanced permeation/diffusion transport in the polarised layer and balanced friction/compaction forces in the deposit. The modelling applied to transient state for dead end filtration gives information about the coupling between mass transfer in the polarised layer and in the deposit. Consequences on specific cake resistance are presented and discussed.
