Electrospun dual-layer nonwoven membrane for desalination by air gap membrane distillation

Graphene/PVDF flat-sheet membrane for the treatment of RO brine from coal seam gas produced water by air gap membrane distillation

“…The phase inverted membranes also presented higher porosity (78.2 to 84.7%) but at smaller mean pore sizes (0.03 to 0.11 µm) compared to C-PVDF membrane (70.3% and 0.22 µm, respectively) [28]. and consequently the phase separation rate leading to sponge-like structure at higher graphene loadings [25].…”

PDMS/PVDF hybrid electrospun membrane with superhydrophobic property and drop impact dynamics for dyeing wastewater treatment using membrane distillation

“…This reliable technique also enables to constructing controllable interfacial surface with inorganic nanomaterials and polymer matrix [12]. The resulting electrospun nanofibrous membranes (ENMs) have high porosity and hydrophobicity, which translates to high permeability and rejection [13]. For this reason, ENMs have gained a great interest as emerging materials for advanced applications of membrane technology such as MD, which requires membranes with hydrophobic, anti-wetting/fouling, and chemically stable properties.…”

Improving Nanofiber Membrane Characteristics and Membrane Distillation Performance of Heat-Pressed Membranes via Annealing Post-Treatment

“…As-spun, heat-pressed and annealed membrane samples was measured with a lab-made setup for their liquid entry pressure [9,24]. A gas supply was connected to a hollow stainless plate by a tube, with a digital gauge standing as the intermediate between them.…”

“…Supported by a PP filter layer, the membrane samples were fixed in the DCMD cell module with a length and width of 77 mm and 26 mm, respectively, making up an effective membrane area of 20 cm 2 , for both feed and permeate channels. The module was placed horizontally and ran in counter-current mode with feed flow on top side [9]. Sodium chloride (NaCl) (3.5 wt.…”
