Title: (DE) REGENWASSERBEHANDLUNGSVORRICHTUNG, -VERFAHREN UND -SYSTEM
(EN) A STORMWATER TREATMENT APPARATUS, METHOD AND SYSTEM
(FR) APPAREIL, PROCÉDÉ ET SYSTÈME DE TRAITEMENT DES EAUX DE PLUIE
Abstract:
(EN) An apparatus and system for stormwater treatment, and a method for controlling a dissolution rate of a flocculating agent in stormwaterare disclosed. The water treatment apparatus comprises a receiving pan having an inlet port, a contact surface and at least one securing element for supporting at least one purification unit having a body defining a plurality of pores and containing a water-soluble flocculating agent. The apparatus further comprises a receiver tank for receiving or collecting the treated water which has passed through the receiving pan, and a tilting structure in order to set an inclination of the contact surface relative a horizontal plane and thereby control a dissolution rate of the flocculating agent when the apparatus is in use. Hereby, a cost-efficient and user-friendly water treatment apparatus is provided.
(FR) La présente invention concerne un appareil et un système de traitement des eaux de pluie, et un procédé permettant de réguler une vitesse de dissolution d'un agent de floculation dans des eaux de pluie. L'appareil de traitement des eaux comprend un bac de réception ayant un orifice d'entrée, une surface de contact et au moins un élément de fixation permettant de supporter au moins une unité de purification ayant un corps définissant une pluralité de pores et contenant un agent de floculation soluble dans l'eau. L'appareil comprend en outre un réservoir récepteur destiné à recevoir ou à recueillir les eaux traitées ayant traversé le bac de réception, et une structure de basculement destinée à régler une inclinaison de la surface de contact par rapport à un plan horizontal et à réguler ainsi une vitesse de dissolution de l'agent de floculation lors d'une utilisation de l'appareil. L'invention permet ainsi de fournir un appareil de traitement des eaux économique et convivial.
