WebSep 5, 2014 · Distilled water permeated flows to the ceramic membranes sintered at 900, 1000, and 1100°C. The membrane that obtained greater water permeated flow was sintered membrane at 1000°C, showing stabilized value of 35.82 kg/h·m 2 after 30 min, followed by the membrane sintered at 900°C with 23.54 kg/h·m 2 and 1100°C with 15.68 kg/h·m 2. WebSep 12, 2013 · When the secondary effluent was filtrated at an elevated permeated flux, the virgin RO membrane exhibited 30% flux decline while the heat-treated membrane showed only 12% flux decline. This is possibly because heat treatment resulted in a denser cross-linked active skin layer, thus reducing the blockage caused by small organic foulants. The process of permeation involves the diffusion of molecules, called the permeant, through a membrane or interface. Permeation works through diffusion; the permeant will move from high concentration to low concentration across the interface. A material can be semipermeable, with the presence of a … See more In physics and engineering, permeation (also called imbuing) is the penetration of a permeate (a fluid such as a liquid, gas, or vapor) through a solid. It is directly related to the concentration gradient of the permeate, a material's See more Abbé Jean-Antoine Nollet (physicist, 1700–1770) Nollet tried to seal wine containers with a pig's bladder and … See more The permeation of films and membranes can be measured with any gas or liquid. One method uses a central module which is separated by the test film: the testing gas is fed on the one side of the cell and the permeated gas is carried to the detector by a sweep … See more • Yam, K.
