Title
(DE) RÜCKSPÜLBARES FILTRATIONSMODUL SOWIE FILTRATIONSANLAGE ZUR REINIGUNG VON PARTIKELBEHAFTETEN FLÜSSIGKEITEN
(EN) BACKFLUSHING FILTRATION MODULE AND FILTRATION SYSTEM FOR CLEANING FLUIDS CONTAMINATED BY PARTICLES
(FR) MODULE DE FILTRATION LAVABLE À CONTRE-COURANT AINSI QU'INSTALLATION DE FILTRATION POUR NETTOYER DES LIQUIDES CHARGÉS DE PARTICULES
Abstract
(DE) Filtrationsanlage zur Reinigung von partikelbehafteten Flüssigkeiten, insbesondere Abwasser, mit mehreren vertikal in Reihe zu einem Rack angeordneten und fluidisch parallel geschalteten Filtrationsmodulen (1a-1c), die je mindestens einen stirnseitigen Zulaufanschluss (2a, 2b) für die zu filtrierende Flüssigkeit sowie mindestens einen Ablaufanschluss (4) für das Filtrat aufweisen, wobei schmutzwasserseitig die zu filtrierende Flüssigkeit über eine zugeordnete gemeinsame Sammelleitung (3a; 3b) an die Zulaufanschlüsse (2a, 2b) gelangt und reinwasserseitig das Filtrat über eine zugeordnete gemeinsame Filtratsammelleitung (5) von den Ablaufanschlüssen (4) abziehbar ist, wobei zum Rückspülen der Filtrationsmodule (1a-1c) mit Filtrat reinwasserseitig im Bereich des Racks ein von außen her mit Druck beaufschlagbarer Elastomerdruckspeicher (6; 6'; 6") integriert ist.
(EN) The invention relates to a filtration system for cleaning fluids contaminated by particles, in particular wastewater, having a plurality of filtration modules (1a-1c) disposed vertically in series in a rack and connected fluidically in parallel, each comprising at least one front end inlet connection (2a, 2b) for the fluid to be filtered, and at least one outlet connection (4) for the filtrate, wherein the fluid to be filtered enters the inlet connections (2a, 2b) via an associated common manifold (3a; 3b) on the dirty water side, and the filtrate can be drawn off from the outlet connections (4) via an associated common filtrate manifold (5) on the clean water side, wherein an elastomer pressure accumulator (6; 6'; 6") under external pressure is integrated in the area of the rack for backflushing the filtration module (1a-1c) with filtrate on the clean water side.
(FR) L'invention concerne une installation de filtration pour nettoyer des liquides chargés de particules, notamment des eaux résiduaires, comprenant plusieurs modules de filtration (1a-1c) qui sont disposés verticalement en rang pour former un bâti et qui comportent chacun au moins un raccordement d'alimentation (2a, 2b) du côté frontal pour le liquide à filtrer ainsi qu'au moins un raccordement de sortie (4) pour le filtrat. Le liquide à filtrer parvient du côté eau sale par l'intermédiaire d'une conduite collectrice commune associée (3a; 3b) aux raccordements d'alimentation (2a, 2b) et le filtrat peut être soutiré du côté eau pure par l'intermédiaire d'une conduite collectrice de filtrat commune associée (5) des raccordements de sortie (4). Un accumulateur de pression élastomère (6; 6', 6") est intégré du côté eau pure dans la région du bâti pour le lavage à contre courant du module de filtration (1a-1c) avec le filtrat.
