Abstract

Dans un aspect, un système de recyclage d'eau comprend un système de surveillance pour la qualité de l'eau, le système de surveillance comprenant un dispositif de mesure de conductivité configuré pour déterminer si l'eau précédemment utilisée dans un cycle d'un lave-linge peut être traitée pour recyclage dans un cycle ultérieur du lave-linge. Le système peut comprendre en outre un système de micro-traitement d'eau configuré pour traiter l'eau précédemment utilisée dans le cycle du lave-linge lorsque le système de surveillance détermine que l'eau peut être traitée pour recyclage, le système de micro-traitement de l'eau comprenant un ou plusieurs filtres, un système de désinfection et une ou plusieurs membranes d'ultrafiltration. Le système peut comprendre en outre un système de commande en communication avec le système de surveillance, le système de micro-traitement de l'eau et le lave-linge, le système de commande comprenant un processeur configuré pour commander le fonctionnement de l'un ou plusieurs parmi le système de surveillance, le système de micro-traitement de l'eau et le lave-linge.
