Abstract: front page image
(EN)An apparatus and method for passively generating a current flow in a body of water is disclosed. The passive water circulating apparatus has an aeration plate having a central opening; a plurality of flotation members joined to the aeration plate, the plurality of flotation members being adapted and disposed for maintaining buoyancy of the aeration plate above a water surface; an uplift tube member having a central orifice in fluid communication with the central opening of the aeration plate; a concentrator member disposed at an end of the uplift tube opposite the aeration plate, the concentrator member having a bottom opening in fluid communication with an upper opening, the bottom opening being wider than the upper opening and the upper opening being connected to the uplift tube member; and a plurality of bio-substrates suspended from the concentrator member below the bottom opening, the plurality of bio-substrates providing a substrate for growth of microbes.
(FR)L'invention concerne un appareil et un procédé pour générer de manière passive un écoulement de courant dans un plan d'eau. L'appareil de circulation de l'eau passive présente une plaque d'aération ayant une ouverture centrale; plusieurs éléments de flottaison réunis à la plaque d'aération, ces éléments de flottaison étant conçus et disposés de manière à maintenir la flottabilité de la plaque d'aération au-dessus d'une surface d'eau; un élément de tube de soulèvement ayant un orifice central en communication fluidique avec l'orifice central de la plaque d'aération; un élément concentrateur disposé à une extrémité du tube de soulèvement à l'opposé de la plaque d'aération, ledit élément concentrateur ayant une ouverture de fond en communication fluidique avec une ouverture supérieure, l'ouverture de fond étant plus large que l'ouverture supérieure et ladite ouverture supérieure étant raccordée à l'élément tube de soulèvement; et une pluralité de bio-substrats suspendus depuis le dessous de l'ouverture de fond de l'élément concentrateur, lesdits bio-substrats fournissant un substrat pour la culture de microbes.
