Abstract
A device for cleaning a fluid comprises at least one set of a first membrane cloth and a second membrane cloth, each being permeable to water over substantially their entire length. The membrane cloths are held taut, substantially parallel to one another in a frame delimiting between them a movement path for fluid. The cloths are displaceable with respect to one another between a first position, in which the mutually facing surfaces substantially touch one another, and a second position, in which the cloths lie at a distance from one another and the width of the movement path for the fluid is greater than in the first position. At least one of the cloths, on the side which faces towards the adjacent cloth is provided with grooves or webs for the purpose of forming channels between the cloths in the longitudinal direction of the cloths, in the first position.
