abstract = {Filter cake formation is the predominant phenomenon
limiting the filtration performance of membrane separation
processes. However, the filter cake’s behavior at the
particle scale, which determines its overall cake behavior,
has only recently come into the focus of scientists, leaving
open questions about its formation and filtration behavior.
The present study contributes to the fundamental
understanding of soft filter cakes by analyzing the
influence of the porous membrane’s morphology on crystal
formation and the compaction behavior of soft filter cakes
under filtration conditions. Microfluidic chips with
nanolithographic imprinted filter templates were used to
trigger the formation of crystalline colloidal filter cakes
formed by soft microgels. The soft filter cakes were
observed via confocal laser scanning microscopy (CLSM) under
dead-end filtration conditions. Colloidal crystal formation
in the cake, as well as their compaction behavior, were
analyzed by optical visualization and pressure data. For the
first time, we show that exposing the soft cake to a
crystalline filter template promotes the formation of
colloidal crystallites and that soft cakes experience
gradient compression during filtration.},
