Method and reactor for flocculation treatment

The treatment procedure, using a flocculation tank (10) and a separation zone, consists of delimiting a central zone (2) in the flocculation tank with the aid of a submerged guide tube (2A) and an agitator (8) in which a turbulent axial flow of the raw fluid and a flocculent is created. The flow is...

Zusammenfassung:	The treatment procedure, using a flocculation tank (10) and a separation zone, consists of delimiting a central zone (2) in the flocculation tank with the aid of a submerged guide tube (2A) and an agitator (8) in which a turbulent axial flow of the raw fluid and a flocculent is created. The flow is divided and distributed by a static device (5A) at the outlet end of the guide tube that opposes its rotation, and the mixture is circulated in a peripheral zone (3) taking it back to the intake end of the central zone, with part of the mixture being passed to the separation zone. The flow in the central zone is maintained at a rate equivalent to between 1 and 20 times the input flow of the raw fluid to be treated, with the flocculent introduced before the fluid enters the tank, in the tank, or in the central zone.
