Abstract

Le dispositif de traitement (1) de l'eau de contre lavage (28) issue d'un filtre à sable (20) de piscine (40) comprend un réservoir de sédimentation (2) délimité par des parois latérales (3), un fond (5) équipé d'un orifice de vidange (7) pour l'extraction de déchets (18) solides après sédimentation de l'eau souillée de contre lavage (28), une entrée adaptée pour recevoir l'eau souillée de contre lavage (28) issue du filtre à sable (20), et une sortie (15) adaptée pour éjecter hors du réservoir (2) l'eau aspirée par un dispositif d'aspiration (16) plongé dans le réservoir (2). Le réservoir (2) comprend en outre un orifice (6) adapté pour l'ajout, à l'intérieur du réservoir (2), de produits de traitement de l'eau de type floculant capables d'agglomérer les souillures et les déchets (18) de l'eau de contre lavage (28), et le dispositif d'aspiration (16) est apte à aspirer une eau « suffisamment propre et claire » (17) après floculation pour la réinjecter directement dans la piscine (40) sans filtrage supplémentaire.The device (1) for treating the backwash water (28) coming from a sand filter (20) for a swimming pool (40) comprises a sedimentation tank (2) delimited by side walls (3), a bottom (5) equipped with a drainage orifice (7) for the extraction of solid waste (18) after sedimentation of the soiled backwash water (28), an inlet adapted to receive the soiled backwash water (28) from the sand filter (20), and an outlet (15) adapted to eject out of the tank (2) the water sucked by a suction device (16) immersed in the tank (2). The reservoir (2) further comprises an orifice (6) suitable for the addition, inside the reservoir (2), of flocculant type water treatment products capable of agglomerating soils and waste ( 18) backwash water (28), and the suction device (16) is able to suck water “sufficiently clean and clear” (17) after flocculation to reinject it directly into the swimming pool (40) without additional filtering.
