Abstract:
(EN) This cross-flow filtration device (10) comprises a filter module (20) having an inner tank (21) and an outer tank (22) that are separated by a semipermeable membrane (23), a treatment liquid tank (30) that accommodates a treatment liquid, a pump (40) that causes the treatment liquid to circulate to the inner tank (21) of the filter module (20) and the treatment liquid tank (30), a supplemental liquid tank (60) that accommodates a supplemental liquid with which the treatment liquid tank is supplemented, at least one or more sensors that measure the pressure of the circulating treatment liquid, and a supplemental liquid measurement unit (80) that measures the amount of the supplemental liquid supplied from the supplemental liquid tank (60) to the treatment liquid tank (30), the supplemental liquid being continuously supplemented to the treatment liquid tank (30).
(FR) Ce dispositif de filtration à écoulement transversal (10) comprend un module de filtrage (20) ayant un réservoir interne (21) et un réservoir externe (22) qui sont séparés par une membrane semi-perméable (23), un réservoir de liquide de traitement (30) qui reçoit un liquide de traitement, une pompe (40) qui amène le liquide de traitement à circuler vers le réservoir interne (21) du module de filtrage (20) et le réservoir de liquide de traitement (30), un réservoir de liquide supplémentaire (60) qui reçoit un liquide supplémentaire avec lequel le réservoir de liquide de traitement est complété, au moins un ou plusieurs capteurs qui mesurent la pression du liquide de traitement circulant, et une unité de mesure de liquide supplémentaire (80) qui mesure la quantité du liquide supplémentaire fourni par le réservoir de liquide supplémentaire (60) au réservoir de liquide de traitement (30), le liquide supplémentaire étant complété en continu dans le réservoir de liquide de traitement (30).
(JA) 本発明のクロスフロー濾過装置(10)は、半透膜(23)で隔てられた内槽(21)と外槽(22)を有するフィルターモジュール(20)と、処理液を収容する処理液槽(30)と、フィルターモジュール(20)の内槽(21)および処理液槽(30)へ処理液を循環させるポンプ(40)と、処理液槽へ補充される補充液を収容する補充液槽(60)と、循環する処理液の圧力を測定する少なくとも1つ以上のセンサと、補充液槽(60)から処理液槽(30)へ供給される補充液の量を測定する補充液測定部(80)と、を備え、補充液が処理液槽(30)へ連続的に補充されている。
