abstract = {We present operando small-angle neutron scattering (SANS)
experiments on silica fouling at two reverse osmose (RO)
membranes under almost realistic conditions of practiced RO
desalination technique. To its realization, two cells were
designed for pressure fields and tangential feed cross-flows
up to 50 bar and 36 L/h, one cell equipped with the membrane
and the other one as an empty cell to measure the feed
solution in parallel far from the membrane. We studied
several aqueous silica dispersions combining the parameters
of colloidal radius, volume fraction, and ionic strength. A
relevant result is the observation of Bragg diffraction as
part of the SANS scattering pattern, representing a
crystalline cake layer of simple cubic lattice structure.
Other relevant parameters are silica colloidal size and
volume fraction far from and above the membrane, as well as
the lattice parameter of the silica cake layer, its volume
fraction, thickness, and porosity in comparison with the
corresponding permeate flux. The experiments show that the
formation of cake layer depends to a large extent on
colloidal size, ionic strength and cross-flow. Cake layer
formation proved to be a reversible process, which could be
dissolved at larger cross-flow. Only in one case we observed
an irreversible cake layer formation showing the
characteristics of an unstable phase transition. We likewise
observed enhanced silica concentration and/or cake formation
above the membrane, giving indication of a first order
liquid–solid phase transformation.},
