ABSTRACT:
In a process for the centrifugal treatment of liquid of liquid or gaseous fluids containing impurities in suspension, of the type in which the fluid to be treated is injected tangentially in a first end of an apparatus of circular transverse section in which this fluid forms a first, substantially cylindrical rotating layer, while at the other end, and starting from the periphery, a fraction containing heavy impurities is collected, then cleared fluid, then possibly a fraction containing impurities lighter than the fluid, it being provided to recycle at least one fraction of the fluid leaving the apparatus by tangential injection into the first end thereof, the fraction to be recycled independently of the initial fluid to be treated is injected at a point located at a radial distance different from that of the point of injection of said fluid, so as to create in the apparatus at least one second, substantially cylindrical layer concentric to the first, in contact therewith and rotating in the same direction substantially according to the same law of variation of the linear speed as a function of the radius.
