Sewer plant for blackwater

摘要

A sewer plant (1) for blackwater (1 a) is provided comprising a collection apparatus (2) of sewage (1 a) from a building and defining an output cross-section (2a) of the sewage (1 a) from said collection apparatus (2); a connection (3) suitable to convey the sewage (1 a) in output from the collection apparatus (2) into a drainage network and defining an input cross-section (3a) of the sewage (1a) in the connection (3) placed at a different height from the output cross-section (2a) so as to receive the sewage (1 a) by gravity; a water wheel (5) defining a rotation axis (5a) and a moment of inertia and comprising radial chambers (5b) suitable to face the cross-sections (2a, 3a) so that when a radial chamber (5b) faces the output cross-section (3a) the sewage (1 a) enters the radial chamber (5b) defining a rotational torque for the water wheel (5) and so that, when such rotational torque is greater than the moment of inertia, the water wheel (5) undergoes a rotation allowing the radial chamber (5b) to face the input cross-section (3a) and, thus the sewage (1 a) in the radial chamber (5b) to enter the connection (3); and an electric generator (6) suitable to convert the rotation of the water wheel (5) into electrical energy.
