摘要

The stairway has a caisson (1) with suction and backflow pipes (4, 5) to mount filtering units along with pumping units for suction and backflow of water in a basin. An independent part (2) is conformed to create steps and risers (2a) and is fixed on the caisson. A body of the stairway defines, after the fixing of the caisson and part, a hollow volume acting as a tank filled with water via openings (2c) of the part for subjecting the water to the action of the filtering units. The pumping units are mounted in an independent compartment fixed to the caisson receiving the filtering units.
