전기투석공정을 이용한 질산성 질소 분리 = Separation of Nitrate Using Electrodialysis Process

다국어 초록 (Multilingual Abstract)

In this study, we evaluate the separation performance of nitrate from water in a recycling batch type electrodialysis (ED) process. In particular, the influences of several operating parameters including the applied current densities and the concentrate concentrations on the ED process performance such as concentrate and dilute concentration profiles, % separation, and energy consumption, were experimentally and theoretically investigated. The two dimensional (2D) batch type ED model based on the extended Nernst-Planck transport theory was used to systematically understand the mass transfer in the ion exchange membrane and the influence of operating conditions on the separation performance. Our results show that the 2D model including the water transport across the membrane is useful to validate the separation of nitrate in different experimental conditions and the concentration behaviors in the concentrate and dilute channels. In addition, the separation performance of nitrate is substantially dependent on the applied current compared to concentrated inlet concentrations.
