Recently, frequent discharge of water-ladened emerging organic pollutants such as Bisphenol A has elicited serious concern due to its pernicious effects on public health and the ecological environment. In this study, hematite nanoparticles (Fe2O3) were synthesized via sol–gel auto-combustion technique incorporated a nanofiller fabricate PVDF-PEG nanocomposite hollow fibre membrane with enhanced...

Membrane filtration performances can be enhanced by the deposition of a selective thin layer on surface porous substrate. Our simulation focus nanometric bicontinuous microemulsions onto hollow-fibre membranes and its polymerisation using UV modules. To that end, laws governing linear liquids have been extended to study microemulsions. highlights difficulty depositing liquid coating fibre witho...

in this research, process asymmetric polyetherimide hollow fiber membranes using ethanol (0, 2 and 4 wt%) as non-solvent additive in the polymer dope via phase inversion method were fabricated. aqueous solution of 1-methyl-2-pyrrolidine (nmp) (90%) was applied as a bore fluid to avoid inner skin layer formation and water was used as the external coagulant. the morphology of fabricated membranes...

Membrane autopsy was performed for a 10 year old polypropylene (PP) hollow fibre microfiltration membrane from Sydney Olympic Park water reclamation plant. The properties of the membrane were studied using scanning electron microscope (SEM) imaging, contact angle, bubble test, thermogravimetric analysis, tensile strength test and functional group. The old and fouled membrane exhibited a signifi...

A multichannel mixed-conducting hollow fibre (MMCHF) membrane, Ba0.5Sr0.5Co0.8Fe0.2O3 δ, has been successfully prepared by a combined phase inversion and sintering technique. Two possible permeation modes can be used in the hollow fibre membrane. One mode is that oxygen permeates from the shell side of the membrane to the lumen side (SL mode), with the other mode being in the direction from the...

Biocatalytic membrane reactors (BMR) combining reaction and separation within the same unit have many advantages over conventional reactor designs. Ceramic membranes are an attractive alternative to polymeric membranes in membrane biotechnology due to their high chemical, thermal and mechanical resistance. Another important use is their potential application in a biphasic membrane system, where...

BACKGROUND AND OBJECTIVE Previous reports of the reduction of fluoride concentrations in fluoridated water by domestic water treatment systems have indicated that further supplementation with fluoride is required. However, the absorption of fluoride by filters has not yet been directly identified. If these filters do not absorb fluoride, further fluoride supplementation may increase fluorosis. ...

This approach was also first described in 1978 by Henderson [16 ]. In this pilot investigation, the reinfu-sion fluid was prepared off-line by dialysis fluid filtration through hollow fibre ultrafilters made of XP-50 membrane and collected in sterile glass carboys before
