Ceramic membranes for wastewater treatment are usually fine filters prepared by sintering of alumina, titania or zirconia powders at ultra-high temperatures and have an asymmetric cross-section using the same material a combination three giving base support active layer forming membrane. The Carman–Kozeny (C–K) Hagen–Poiseuille (H–P) transport equations been used to predict water permeability c...

In this paper, a system for efficient removal of carbon dioxide by hollow fiber membranes is proposed. The system is compact, and it is very useful for application in the offshore energy industries. In particular, it is used to removing CO2 from the exhaust of power generation facilities on offshore platforms.The proposed dual membrane contactor contains two types of membranes (polypropylene me...

The polysulfone-based membrane has been used in hemodialysis (HD) and it is continuously developed to maintain its sustainability on the subject of biocompatibility. During the polysulfone-based membrane development, several parameters should be considered to improve the membrane performances, such as excellent biocompatibility, appropriate ultrafiltration rate, and effective clearance of the t...

A transparent model cell for direct ex-situ visualization of the dynamic characteristics growth, deformation and detachment liquid water in flow channel proton exchange membrane fuel (PEMFC) is designed. It fulfills requirements clear side imaging droplet behaviors channel. Different air velocities are implemented experiments to measure growth on gas diffusion layer (GDL) surface. The results s...

Graphene oxide (GO) membranes have shown promising gas separation characteristics that make them of interest for large-scale industrial applications. However, the gas transport mechanism for GO membranes is unclear due to inconsistent permeation and separation results reported in literature. GO membranes examined for gas separation were prepared on substrates and/or by synthesis methods that ar...

Abstract Membrane distillation (MD) is a desalination technique that uses membrane to thermally separate potable water from sea or brackish water. The mass transport processes through the are commonly described by dusty gas model. These modeled assuming uniform, ideally cylindrical capillaries and adjusted for geometry including porosity tortuosity. tortuosity usually set 2 used as an adjusting...

Gas-liquid membrane contactors offer several practical advantages including high surface area per unit volume; independent control of gas and liquid velocities without any flooding, loading, weeping, or foaming, pre-determined gas–liquid interfacial area, membrane modules, capability of linear scale-up; low corrosion problems, and low operation and capital costs. Two common types of membrane co...

Partial oxidation of methane (POM) is a prominent pathway for syngas production, wherein the hydrogen in product can be recovered directly from reaction system using (H2)-permeable membrane. Enhancing efficiency this H2 separation process current major challenge. In study, Ce0.8Y0.2O2-δ-BaCe0.8Y0.2O3-δ (YDC-BCY) hollow fiber (HF) membranes were developed and characterized their permeation fluxe...

We demonstrate and explain a simple and efficient way to remove gas bubbles from liquid-filled microchannels, by integrating a hydrophobic porous membrane on top of the microchannel. A prototype chip is manufactured in hard, transparent polymer with the ability to completely filter gas plugs out of a segmented flow at rates up to 7.4 ll/s/mm of membrane area. The device involves a bubble genera...

The separator is a critical component for the performance of alkaline water electrolysis as it ensures ionic contact between electrodes and prevents product gases from mixing. While conductivity affects cell voltage, permeability dissolved influences gas impurity. Currently, diaphragms are used separators, pore system which filled with electrolyte solution to enable exchange ions. breakthrough ...
