Based on the results of in vitro studies of many experimental models, a silicone hollow fiber membrane oxygenator for pediatric cardiopulmonary bypass (CPB) and extracorporeal membrane oxygenation (ECMO) was developed using an ultrathin silicone hollow fiber with a 300 microm outer diameter and a wall thickness of 50 microm. In this study, we evaluated the gas transfer performance of this oxyge...

Abstract In this study, a mathematical model is proposed for CO2 separation from N2/CO2 mixtureusing a hollow fiber membrane contactor by various absorbents. The contactor assumed as non-wetted membrane; radial and axial diffusions were also considered in the model development. The governing equations of the model are solved via the finite...

Membrane distillation (MD) has received much attention in recent years as an alternative technology for the removal of volatile compounds from industrial waters. The microporous hydrophobic membrane utilised in MD allows only vapour passing through and the process selectivity is essentially determined by the liquid-vapour equilibrium conditions existing at the liquid-membrane interface. In this...

This study aims to investigated the effect of aeration mode on membrane bioreactors (MBRs) using a self-designed integrated hollow fiber MBR and flat sheet organic for rural greywater treatment. The pollutant removal efficiency, characteristics activated sludge mixed liquor, mechanisms fouling were systematically analyzed under intermittent continuous modes. results indicate that permeability M...

The high hydrophobicity of poly(vinylidene fluoride) (PVDF) membrane remains an obstacle to be applied in some purification processes of water or wastewater. Herein, a highly hydrophilic hybrid mesoporous titania membrane composed of mesoporous anatase titania (meso-TiO2) materials inside the three-dimensional (3D) macropores of PVDF membrane was successfully prepared by using the dual-template...

The polyvinylidene fluoride (PVDF)/Fe 3+ -TiO2 catalytic membrane was prepared by sol-gel method. It was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), FT-IR spectrum (FT-IR), mechanics capability, water flux, pepsin retention, porosity and contact angle etc. The catalytic activity of PVDF/Fe 3+ -TiO2 catalytic membrane was evaluated by the degradation of refracto...

Humidity sensors have been widely used in areas such as agriculture, environmental conservation, medicine, instrumentation and climatology. Hydrophobicity is one of the important factors in capacitive humidity sensors: recent research has shown that the inclusion of graphene (G) in polyvinylidene fluoride (PVDF) improves its hydrophobicity. In this context, a methodology to fabricate electrospu...

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...
