The invention provides a cross-flow separation element comprising a single-piece rigid porous support (2) having within its volume at least one channel (4.sub.1) for passing a flow of the fluid medium for treatment, which channel presents a flexuous flow volume (V1) defined by sweeping a generator section along a curvilinear path around a reference axis, and in that the reference axis does not intersect said generator section and is contained within the volume of the porous support.

The present disclosure relates, according to some embodiments, to systems, apparatus, and methods for fluid purification (e.g., water) with a ceramic membrane. For example, the present disclosure relates, in some embodiments, to a cross-flow fluid filtration assembly comprising (a) membrane housing comprising a plurality of hexagonal prism shaped membranes (b) an inlet configured to receive the contaminated fluid and to channel a contaminated fluid to the first end of the plurality of hexagonal prism shaped membranes, and (c) an outlet configured to receive a permeate released from the second end of the plurality of hexagonal shaped membranes. The present disclosure also relates to a cross-flow fluid filtration module comprising a fluid path defined by a contaminated media inlet chamber, a fluid filtration assembly positioned in a permeate chamber and a concentrate chamber.

The present invention relates to a particulate material separation assembly. It comprises a filtration membrane and an antifouling device. The antifouling device comprises one or more magnets and a plurality of magnetisable particles. The one or more magnets cause the plurality of magnetisable particles to self-assemble into dynamic bristles, thereby forming a brush. The particulate material separation assembly is particularly useful in the context of micro algae harvesting.

In one aspect, separation media are described herein operable for removing one or more water contaminants including NOM and derivatives thereof. Briefly, a separation medium includes a nanoparticle support and an oligomeric stationary phase forming a film on individual nanoparticles of the support, the film having thickness of 1 to 100 nm. In some embodiments, oligomeric chains of the stationary phase are covalently bonded to the individual nanoparticles.

A piece of substrate material is formed under heat and pressure by a roller against a cavity or platen into a shaped substrate sheet having one or more depressions. Two substrate sheets are bonded together to form a substrate wherein the one or more depressions form one or more interior channels. The substrate is coated with a dope in a casting device having a guide portion corresponding to the shape of the substrate sheets and quenched to form a filtering membrane.
