Title
(DE) FILTRATIONSANLAGE MIT MEHREREN PARALLEL GESCHALTETEN FILTRATIONSMODULEN
(EN) FILTRATION SYSTEM COMPRISING A PLURALITY OF FILTRATION MODULES CONNECTED IN PARALLEL
(FR) INSTALLATION DE FILTRATION DOTÉE DE PLUSIEURS MODULES DE FILTRATION RACCORDÉS EN PARALLÈLE
Abstract
(DE) Filtrationsanlage mit mehreren vertikal in Reihe angeordneten und parallel geschalteten Filtrationsmodulen (1a bis 1c), woran mindestens ein stirnseitiger Zulauf (2a, 2b) für die zu filtrierende Flüssigkeit angeordnet ist, die je zugeordnete sich längs erstreckende Sammelleitungen (3a bzw. 3b) speisen, wobei jedes Filtrationsmodul (1a bis 1c) mindestens einen Ablauf (4) für das Filtrat aufweist, welche in eine gemeinsame Filtratsammelleitung (5) münden. Hierbei ist die die Filtrationsmodule (1a bis 1c) miteinander verbindende Filtratsammelleitung (5) als Rückspülbehälters ausgebildet, wobei zum Rückspülen in die Filtratsammelleitung (5) eingeleitete Druckluft das Wasser aus der Filtratsammelleitung (5) in die Filtrationsmodule (1a bis 1c) verdrängt.
(EN) Filtration system comprising a plurality of filtration modules (1a to 1c) arranged vertically in series and connected in parallel, on which is arranged at least one end feed (2a, 2b) for the liquid to be filtered, which is fed by collecting lines (3a and 3b) which extend longitudinally and are assigned to each, each filtration module (1a to 1c) having at least one outlet (4) for the filtrate, which open into a common filtrate collecting line (5). At the same time, the filtrate collecting line (5) which connects the filtration modules (1a to 1c) to one another is configured as a back-rinsing vessel, and, for the purpose of back-rinsing, compressed air introduced into the filtrate collecting line (5) displaces the water from the filtrate collecting line (5) into the filtration modules (1a to 1c).
(FR) L'invention concerne une installation de filtration qui présente plusieurs modules de filtration (1a à 1c) disposés verticalement en série et raccordés en parallèle, sur laquelle est disposée au moins une amenée frontale (2a, 2b) du liquide à filtrer qui alimente des conducteurs de collecte (3a ou 3b) qui lui sont associés et qui s'étendent longitudinalement, chaque module de filtration (1a à 1c) présentant au moins une évacuation (4) de filtrat qui débouche dans un conduit commun (5) de collecte de filtrat. Le conducteur (5) de collecte de filtrat qui relie les uns aux autres les modules de filtration (1a à 1c) est configuré comme récipient de rinçage, et pour le rinçage, de l'air comprimé introduit dans le conduit (5) de collecte de filtrat refoule l'eau du conduit (5) de collecte de filtrat pour l'envoyer dans les modules de filtration (1a à 1c).
