Abstract
A purification plant comprises a vessel 1 in which the liquid or sewage 2 being treated is placed, means 3, 5 for generating a flow of air in that liquid 2 and means 23, 24 capable of delivering sewage to the said vessel. According to the invention the abovementioned plant comprises at least one concave member 8 located in vessel 1 with the concavity facing the bottom 10 thereof, the said member 8 being placed above the zone in which the air flow is generated in the form of bubbles 7 which lift the sewage 2 towards the surface; abovementioned member 8 stops this rise and creates an air pocket 13 such as to transfer a greater quantity of oxygen to the bacterial substances or sludges usually dissolved in the liquid being treated so as to ensure greater purification from polluting substances.
