The invention relates to a device, in particular suitable for cleaning a fluid, such as water, comprising at least one set (2) of a first membrane cloth (21) and a second membrane cloth (22), each being permeable to water over substantially their entire length, which membrane cloths (21, 22) are held taut, substantially parallel to one another in a frame (1), the membrane cloths (21, 22) between them delimiting a movement path for fluid, the cloths (21, 22) being displaceable with respect to one another between a first position, in wich the mutually facing surfaces substantially touch one another, and a second position, in which the cloths (21, 22) lie at a distance from one another and the width of the movement path for the fluid is greater than in the first position, in which device at least one of the cloths (21, 22), on the side which faces towards the adjacent cloth (21, 22), is provided with grooves (25) or webs for the purpose of forming channels between the cloths (21, 22) in the longitudinal direction of the cloths, in the first position of the membrane cloths (21, 22).
L'invention concerne un dispositif destiné notamment à nettoyer un fluide, tel que de l'eau, comprenant au moins un ensemble (2) constitué d'une première garniture (21) membranaire et d'une seconde garniture (22) membranaire. Ces garnitures (21, 22) membranaires sont perméables à l'eau sur sensiblement toute leur longueur et sont maintenues rigides, sensiblement parallèles entre elles dans une structure (1). La garniture 21, 22) membranaire située entre elles délimite un chemin de mouvement pour le fluide, les garnitures pouvant être déplacées les unes par rapport aux autres entre une première position, dans laquelle les surfaces se faisant face se touchent sensiblement, et une seconde position, dans laquelle les garnitures (21, 22) reposent à distance les unes des autres et la largeur du chemin de mouvement pour le fluide est plus importante que dans la première position. Dans ledit dispositif, au moins l'une des garnitures (21, 22), sur le côté qui fait face à la garniture adjacente, est pourvue de sillons (25) ou de bandes servant à former des canalisations entre la garniture (21, 22) dans le sens longitudinal des garnitures, dans la première position des garnitures membranaires (21, 22).
