The device has a transversal plane section module (4) with less thickness delimiting internal emerging pipes. The pipes include tight connection arrangements with nozzles (5). The nozzles are integrated with suction pipes and back-flow pipes (2). A filtration unit is connected in combination with the pipes. The module is arranged between two compartments at the level of a common part that overlaps sides of a tank/pool. |
