<p>It is characterised in that it incorporates U-shaped hollow fibre membranes arranged in parallel planes, at the same time as they filter the sludge water and which are coupled via their lowest part to some slots of a lower structure with aeration holes, while via their upper part they discharge into and are connected to an upper head which incorporates at least one suction pipe, the head and the lower structure being joined by means of some guide rods with the aid of some nuts. It is also characterised in that the hollow fibre membranes are arranged in concentric groupings in a single plane, thereby obtaining a greater filtration surface without increasing the space of the module. It is furthermore characterised in that it incorporates a permanent tensioning device capable of absorbing the variations in length undergone by the hollow fibre membranes.</p> |
