Кроме того, на практике обнаруживается противоречие в практике – повышение скачка потенциала в существующих ЭМС не обеспечивает интенсификации переноса ионов соли при сверхпредельных токовых режимах.</p><p>Статья посвящена исследованию влияния одного из деструктивных явления – пробоя пространственного заряда на производительность электромембранных систем в сильно разбавленных солевых растворах. Целью работы является теоретическая оценка влияния пробоя пространственного заряда на перенос ионов соли в электромембранных системах.</p><p>Разработана математическая модель на основе уравнений Нернста-Планка и Пуассона. Рассмотрен процесс электродиализного обессоливания раствора NaCl, находящегося в проточной камере между анионообменной мембраной (АЭМ) и катионообменной мембраной (КЭМ). Поток раствора направлен снизу вверх. Проведено численное моделирование влияния пробоя пространственного заряда на производительность ЭМС в сильно разбавленных солевых растворах.</p><p>Разработана новая математическая модель и программное обеспечение для численного моделирования влияния пробоя пространственного заряда на производительность ЭМС в сильно разбавленных солевых растворах.</p><p>В работе с помощью 2D математической модели и формулы вольтамперной характеристики канала обессоливания впервые определено влияние пробоя пространственного заряда на перенос ионов соли в электромембранных системах при различных значениях скачка потенциала. Определены диапазоны токов, которые соответствуют высокому и незначительному росту производительности электромембранных систем, а также диапазон токов, в котором рост отсутствует. Полученные результаты можно использовать для определения оптимального значения скачка потенциала по критерию максимальной производительности. Полученные результаты могут быть применены для проектирования промышленных ЭМС для интенсификации массопереноса и увеличения производительности.</p></abstract><trans-abstract xml:lang="en"><p>It is known that the existing methods of using electromembrane systems (EMS) do not allow the most efficient water treatment and water treatment at overlimiting current modes, which is why there is a need to determine the operating parameters of electrodialysis plants to prevent complex destructive effects, it is essential limiting mass transfer, and reducing the efficiency of EMS. In addition, in practice, a contradiction is found in practice - an increase in the potential jump in the existing EMS does not provide an intensification of the transfer of salt ions under overlimiting current modes.</p><p>The article is devoted to the study of the influence of one of the destructive phenomena - the breakdown of the space charge on the performance of electromembrane systems in highly diluted salt solutions. The aim of this work is a theoretical assessment of the effect of space charge breakdown on the transport of salt ions in electromembrane systems.</p><p>A mathematical model based on the Nernst-Planck and Poisson equations has been developed. The process of electrodialysis desalination of a NaCl solution located in a flow chamber between an anion exchange membrane (AEM) and a cation exchange membrane (CEM) is considered. The solution flow is directed from bottom to top. Numerical modeling of the effect of space charge breakdown on EMS performance in highly dilute salt solutions has been carried out.</p><p>The new mathematical model and software have been developed for numerical simulation of the effect of space charge breakdown on EMS performance in highly dilute salt solutions.</p><p>In this work, using a 2D mathematical model and the formula for the current-voltage characteristic of the desalination channel, the effect of space charge breakdown on the transfer of salt ions in electromembrane systems at various values of the potential jump was determined for the first time. The ranges of currents are determined, which correspond to a high and slight increase in the performance of electromembrane systems, as well as a range of currents in which there is no increase. The obtained results can be used to determine the optimal value of the potential jump according to the criterion of maximum productivity. The results obtained can be applied to the design of industrial EMC to intensify mass transfer and increase productivity.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ионообменная мембрана</kwd><kwd>электродиализ</kwd><kwd>пробой пространственного заряда</kwd><kwd>сверхпредельный ток</kwd><kwd>вольтамперная характеристика</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ion-exchange membrane</kwd><kwd>electrodialysis</kwd><kwd>space charge breakdown</kwd><kwd>overlimiting current</kwd><kwd>current- voltage characteristic</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при финансовой поддержке РФФИ и DFG в рамках научного проекта № 20-58-12018 ННИО_а</funding-statement><funding-statement xml:lang="en">The study was carried out with the financial support of the RFBR and DFG within the framework of the scientific project № 20-58-12018 ННИО_а</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Nikonenko, V.
