Web5 apr. 2024 · In a partially ionized plasma, the collisions tie the neutrals to the charges and hence to B. In other words, neutrals indirectly feel magnetic forces due to the collisional coupling. However, as collision frequencies reduce—at lower densities or temperatures, for example—there can be some drift between species. WebBecause an ED system removes only ionized species, it is particularly suitable for separating non-ionized from ionized components. How Does Electrodialysis Work? The function of Electro Dialysis is to divide the input water into concentrated (reject) and dilute (product) streams, transporting dissolved ions by an electrical force.
