Abstract

La présente invention concerne un "Système de classification et de filtrage total d'eau pluviale captée" (100) destiné à l'utilisation des eaux pluviales. Le système est capable d'éliminer l'eau trouble/sale avant de commencer le procédé de filtrage, ce qui économise l'élément filtrant (31), augmentant ainsi sa vie utile. Cela est possible grâce aux dispositifs de surveillance de l'eau à l'intérieur d'une chambre de lecture (22), qui réalisent une lecture de paramètres du flux d'eau, de sorte qu'un module de commande (60) analyse et classifie l'eau captée, mettant ou non l'élément filtrant (31) dans une position d'actionnement. Le module de commande (60) peut être programmé pour sélectionner l'eau selon des paramètres variés, en fonction de l'application finale à attribuer à l'eau captée. Ce système (100) permet de surveiller la concentration de résidus accumulés dans l'élément filtrant (31), réalisant un cycle d'auto-nettoyage, évitant le gaspillage constant de l'eau.
