<p>1. Profile made from synthetic material for a motorized biological filter intended for a purification installation, characterized by the fact that it has a series of cells of practically square cross-section, which are demarcated by two plane walls (1, 2) and by perpendicular partitions (3, 4), one of its edges comprising a face (8) along which there is a longitudinal recess (9) in which the blades (5, 6) of an adjacent identical profile are able to engage, so that it is possible to construct a continuous, flexible band made up of profiles assembled together and capable of being wound in a roll around a central cylindrical core in order to make up the body of the rotary filter.</p> |
