A three-dimensional computational fluid dynamics model of a proton exchange membrane fuel cell (PEMFC) with both gas distribution flow channels and Membrane Electrode Assembly (MEA) is developed. A set of conservation equation is numerically solved by developing a CFD code based on the finite volume technique and SIMPLE algorithm. In this research, some parameters like oxygen consumption, water...

membrane assisted liquid extraction(male) technologies are gaining an important role as an extraction /separation technique for actinides and are being deployed as a  promising tool for remediation of nuclear waste generated in the reprocessing plant and other radioactive wastes containing a trace level of radionuclides. the present contribution outlines the classification of membrane assisted ...

We describe a new on-line sensitive and selective procedure for the determination of trivalent hexavalent chromium in liquid samples by tailor-made contactor (TMC), specifically membrane annular TMC, coupled with inductively plasma optical detection. The TMC was designed developed to integrate extraction stripping phases analyte one module minimize solvent’s consumption maximize speed transport...

A new HIGEE device-rotating zigzag bed (RZB) was developed in the context of process intensification. The RZB is structurally featured by a combinatorial rotor of one series of baffles attached to a rotating disk with another series to a stationary disk. The novel structure of the RZB determines its many advantages over the other HIGEE devices. The RZB is free of dynamic seal, capable of interm...

The improvement of an innovative dual membrane contactor process for treatment of combined hygiene and metabolic wastewater was investigated. Flux and solute rejection in the combined direct osmosis/osmotic distillation (DO/OD) process were enhanced by incorporating membrane distillation (MD) concepts into the process. Two new configurations were investigated: DO/MD, in which the driving force was

introduction membrane bioreactor (mbr) is an effective technology for wastewater treatment and water reuse which is becoming increasingly popular due to its numerous applications and advantages over conventional activated sludge process. this novel technology have advantages of small footprint, high concentration of mixed liquor suspended solids (mlss), high removal efficiency of chemical oxyge...
