Membrane tortuosity
Web9 dec. 2024 · The membrane acts as a barrier between the liquid and the gas phases and the mass transfer occurs by diffusion (and not by dispersion) due to a concentration gradient [ 36 ]. The ozone, therefore, gets uniformly transferred to the water to be treated via a bubbleless process. WebThree membranes with a different and ion-exchange capacity are analyzed. The heterogeneous structure of the membranes shows a random distribution of sulfonated (hydrophilic) and non-sulfonated (hydrophobic) domains, whose proton conductivity is modeled based on percolation theory.
