Title (EN) INTEGRATED UNIT FOR INTAKE AND PRETREATMENT WITH LOCAL BACKWASHING
(FR) UNITÉ INTÉGRÉE POUR PRÉLÈVEMENT ET PRÉTRAITEMENT À LAVAGE À CONTRE-COURANT LOCAL
Abstract:
(EN) Locally backwashing portions of filter media allows a simple and effective design of intake and pretreatment units, as well as their integration. An enclosure is used to limit portions of filter media and backwash them locally by suction, utilizing filtered water from adjacent filter media as the back wash water. Wastewater is produced at small amounts that allows efficient sludge treatment. This design enables water pretreatment at the intake unit, simplifying overall plant design and preventing damage to organisms living outside the intake unit.
(FR) Selon l'invention, le lavage à contre-courant local de parties de matériau filtrant permet une conception simple et efficace d'unités de prélèvement et de prétraitement, ainsi que leur intégration. Une enceinte est utilisée pour limiter des parties de matériau filtrant et les laver à contre-courant localement par aspiration, à l'aide d'eau filtrée provenant de matériau filtrant adjacent utilisée comme eau de lavage à contre-courant. De l'eau résiduaire est produite en petites quantités ce qui permet un traitement efficace des boues. Cette conception permet le prétraitement d'eau au niveau de l'unité de prélèvement, la simplification de la conception globale de l'installation et la prévention d'une atteinte à des organismes vivant à l'extérieur de l'unité de prélèvement.
