Title (EN) LIQUID PURIFICATION SYSTEM
(FR) SYSTÈME DE PURIFICATION DE LIQUIDE
(RU) СИСТЕМА ОЧИСТКИ ЖИДКОСТИ
Abstract:
(EN) The invention relates to systems for membrane purification and/or demineralization with recirculation of liquid, primarily water. The system comprises an untreated liquid line with a pump mounted thereon, a membrane element connected to a purified liquid line and to a liquid recirculation line having a pressure regulator mounted thereon and furthermore being connected to a liquid drainage line, and a controller, and is capable of spontaneously maintaining a pressure of not less than is necessary for carrying out a filtration process as a result of the pressure regulator being in the form of a mechanical spring-loaded valve. Furthermore, untreated liquid is always supplied at a greater ratio rate than the overall rate of removing purified liquid and drainage.
(FR) L'invention concerne des systèmes de purification par membrane et/ou de désalinisation de liquide, principalement de l’eau. Le système comprend une conduite de liquide initial sur laquelle est montée une pompe, un élément membrane relié à la conduite de liquide purifié et une conduite de circulation de liquide sur laquelle est monté un régulateur de pression relié à la conduite pour liquide de drainage et un contrôleur ; le système est réalisé de manière à maintenir la pression égale ou supérieure à la pression pour effectue la filtration grâce à la réalisation du régulateur de pression sous la forme d’une soupape mécanique précontrainte. Le rapport de la vitesse d'amenée de liquide initial au débit global de prélèvement de liquide purifié et de drainage est toujours supérieur.
(RU) Изобретение относится к системам мембранной очистки и/или обессоливания с рециркуляцией жидкости, преимущественно воды. Система содержит линию исходной жидкости с установленными на ней насосом, мембранный элемент, соединенный с линией очищенной жидкости и линией рециркуляции жидкости, с установленным на ней регулятором давления, соединенной при этом с линией дренажной жидкости, и контроллер, и выполнена с возможностью самопроизвольного поддержания давления не меньше, чем необходимое для осуществления процесса фильтрации, за счет того, что регулятор давления выполнен в виде механического подпружиненного клапана. При этом отношение скорости подачи исходной жидкости к суммарной скорости отбора очищенной жидкости и дренажа всегда больше.
