PURPOSE: To enhance separation efficiency by simultaneously performing separation and washing, by rotating a rotor having a filter and three or more of chambers, and enabling the change-over of the relation of each chamber and both fixed casings of a fluid to be treated and treated fluid.
CONSTITUTION: A fluid to be treated is flowed into one chamber of a rotor 11, which has a magnetic filter element and is provided with three or more of mutually paritioned chambers, from an inflow pipe 5. In this case, a zigzag stream is repeated through a connection flowline S and supplied to the other chamber to which a magnetic field is applied by a magnetic field applying apparatus 1 while magnetic particles in the fluid to be treated are separated and the treated fluid is discharged from a fluid outflow pipe 6. On the other hand, a washing fluid is supplied to the chamber, into which the fluid to be treated is supplied, from an inflow pipe 7 through a washing fluid jet orifine 15 and magnetic particles are washed off from the filter element to be discharged from an outflow pipe 8. Subsequently, the rotor 1 is rotated and the aforementioned cycle is repeated.
