Abstract

L'invention concerne un système d'épuration d'eau qui permet d'obtenir une longue durée de vie des filtres. Ce système d'épuration d'eau contient au moins un moyen d'utilisation qui, lorsque de l'eau introduite dans le système est utilisée, évacue l'eau résiduaire en tant qu'eaux usées. Le système d'épuration d'eau comprend : un filtre à écoulement transversal 12 qui purifie les eaux usées provenant d'une cabine de douche 21; et un réservoir 14 de stockage d'eau qui est positionné avant le filtre à écoulement transversal 12. Le réservoir de stockage d'eau 14 stocke les eaux usées qui n'ont pas été purifiées par le filtre à écoulement transversal 12. La cabine de douche 21 utilise de l'eau purifiée par le filtre à écoulement transversal 12.
