Webb12 apr. 2024 · Recently, the reverse osmosis (RO) process is widely used in the field of desalinating brackish water and seawater to produce freshwater, but the disadvantage of using this technology is the increase in the rates of electrical energy consumption necessary to manage these units. To reduce the rates of electrical energy consumption … WebbThe thermo-osmosis of gases through a membrane. I 379 2. Classical thermodynamics applied to thermo-osmosis We consider a gas in contact with a membrane in which it is slightly soluble. Let the two membrane surfaces be at temperatures and T2 respectively, and let the corresponding gas pressures, in the two vessels, be and stationary state

Webb2 juli 2004 · The thermo‐osmosis is an electro‐osmotic flow caused by the electric field which is set up in the membrane so that no net electric charge is allowed to be transported across the membrane. The dependence of the electro‐osmotic coefficient on salt concentration is the primary cause for the characteristic behavior of the thermo‐osmosis … Webb9 nov. 2012 · In forward osmosis (FO), an osmotic pressure gradient generated across a semi-permeable membrane is used to generate water transport from a dilute feed solution into a concentrated draw solution. This principle has shown great promise in the areas of water purification, wastewater treatment, seawater desalination and power generation. …
WebbThe thermo-osmosis of a gas through a polymer membrane, in which it dissolves, occurs if a temperature gradient is imposed across the membrane. The derivation is presented of equations for the gradual change of the pressure difference across the film towards an eventual steady state. They extend beyond those of Denbigh and Raumann, who …
WebbIt is shown that pore-water pressure evolution can be considerably affected by thermo-osmosis. Under the conditions of the problem considered, it was found that thermo-osmosis changed the pore-water pressure regime in the vicinity of the heater when the value of thermo-osmotic conductivity was larger than 10 −12 m 2 ·K −1 ·s −1. cranial nerve functionsWebbThe only well-authenticated instance of a purely thermal migration of a liquid against a hydrostatic pressure, through a permeable barrier, is the fountain effect of He I. This process, like the thermo-osmosis and thermal effusion phenomena of gases, gives rise to a well-defined stationary pressure difference. diy shirt paintingWebb26 jan. 2012 · thermo-osmosis The movement of liquid in a porous medium due to differences in temperature.
