Operating conditions and feed composition on filtering emulsified oil using ceramic-hybrid membrane

A Systematic Literature Review of Ceramic Membranes Applications in Water Treatment

“…Zhao et al obtained a 100% rejection when using pristine and CNTN-ZrO membranes but the flux of CNTN-ZrO membrane was higher as shown in Fig. 11 (c) and (d) [92]. Using CNTs improved the membrane performance because they reduced the formation of gel layer, then reduce the flow resistance.…”

Flexible Mesoporous Membranes with Revivability and Superwettability for Sustainable Oil–Water Separation

“…Significant efforts have been given to the separation of water and dispersed oils (20–150 μm) via the application of special wettable membranes. − However, the challenging separation of stable oil–water emulsions with small droplet diameters (<20 μm), especially for surfactant-stabilized oil–water emulsions with lower interfacial tension, needs further comprehensive research studies. , Numerous reported approaches have been advanced to prepare membrane materials with wettability to separate oil–water emulsions, for instance, chemical etching, electrodeposition, self-assembly, electrospinning, etc. − Thereinto, electrospinning as a rapidly developing technology has been attracting tremendous attentions in oil–water separation in view of the tunable porosity, adjustable structures, and controllable morphology of the electrospun nanofiber-based membrane, not only benefiting the precise manipulation of the surface roughness but also facilitating the increase of permeation fluxes, thereby endowing performance enhancement in emulsion separation . In particular, inorganic electrospun composite membranes with superwettability have been extensively reported for oily wastewater remediation. , …”

“…13 In particular, inorganic electrospun composite membranes with superwettability have been extensively reported for oily wastewater remediation. 14,15 Taking inspiration from nature, such as fish skin and the surface of the Nepenthes pitcher plant, a novel kind of liquidinfused surface has been developed since 2011, which provided a fascinating and powerful strategy for liquid separation. 16 In the same year, Jiang's group first fabricated a superhydrophilic/ underwater superoleophobic membrane (referred to as an "oilblocking" membrane), which formed a water-infused surface to repel immiscible oils.…”
