Abstract
A method for purifying a fluid from contaminating particles in a centrifugal separator with use of a separation aid which is of higher density than the fluid and which binds said particles, the centrifugal separator having a rotor body that rotates about an axis of rotation. The fluid to be purified is led via an inlet into a separation chamber delimited by the rotor body. Separated particles are discharged via a first outlet and clarified fluid cleared is discharged via a second outlet. The fluid being mixed with an amount of separation aid, supplied to the separation chamber. The pollutant particles are bound to the separation aid, which is forced out by the rotation of the rotor body to the periphery thereof. A small flow of separation aid and particles bound thereto are discharged from the separation chamber via the first outlet, and a flow of purified fluid is discharged from the separation chamber via the second outlet.
