Title
(EN) SYSTEMS AND METHODS FOR PURIFYING NATURAL WATER FOR RECREATIONAL SWIMMING WITH MODULAR FILTRATION UNITS
(FR) SYSTÈMES ET PROCÉDÉS DE PURIFICATION D'EAU NATURELLE POUR LA NATATION RÉCRÉATIVE AU MOYEN D'UNITÉS DE FILTRATION MODULAIRES
Abstract
(EN) Systems and methods for filtering unpurified water using modular filtration units are disclosed. According some embodiments of the invention the modular filtration unit may include a modular removable filtration cartridge with pressed non-woven geotextile fabrics and a frame assembly, and a filtration container. The filtration container holds the modular removable filtration cartridges and has walls that form a basin. A first wall has an inlet for receiving water into the filtration container and a second wall has an outlet for draining water out of the filtration container. The water is filtered by the modular removable filtration cartridges as it flows across the basin from the inlet to the outlet. The modular filtration units may be combined together to form a zoned filtration assembly, which may be inserted into the hull of a floating swimming pool. The zoned filtration assemblies may filter natural water as it fills the swimming pool.
(FR) L'invention concerne des systèmes et des procédés pour filtrer de l'eau non purifiée à l'aide d'unités de filtration modulaires. Selon certains modes de réalisation de l'invention, l'unité de filtration modulaire peut comprendre une cartouche de filtration amovible modulaire avec des toiles de géotextile non tissées pressées, un ensemble cadre et un réservoir de filtration. Le réservoir de filtration contient les cartouches de filtration amovibles modulaires et comporte des parois qui forment un bassin. Une première paroi possède une entrée pour recevoir de l'eau dans le réservoir de filtration et une seconde paroi possède une sortie pour évacuer l'eau hors du réservoir de filtration. L'eau est filtrée par les cartouches de filtration amovibles modulaires lorsqu'elle s'écoule à travers le bassin depuis l'entrée jusqu'à la sortie. Les unités de filtration modulaires peuvent être combinées pour former un ensemble de filtration zoné, qui peut être inséré dans la coque d'une piscine flottante. Les ensembles de filtration zonés peuvent filtrer de l'eau naturelle lors du remplissage de la piscine.
