摘要：A dispersing system comprises a dispersing apparatus, a storage tank forstoring a dispersing medium and a liquid containing a material to be treated, and conduitsfor connecting the dispersing apparatus in fluid communication with the storage tank.The dispersing apparatus comprises a dispersing chamber, at least one rotationallydriven disc, a suction inlet through which the liquid containing the material to be treatedand the dispersing medium are drawn from the storage tank into the dispersing chamberby the suction created by rotation of the disc, a discharge outlet, and a medium-separating device for separating the dispersing medium from the liquid containing thedispersed material and selectively discharging the liquid containing the dispersedmaterial but not the dispersing medium from the discharge outlet. During a dispersingtreatment, the liquid containing the material to be treated and the discharge medium aredrawn by suction from the storage tank into the dispersing chamber through one of theconduits by the rotation of the disc. The dispersing medium is then circulated within thedispersing chamber by the rotation of the disc to disperse the material to be treated inthe liquid. Thereafter, the liquid containing the dispersed material but not the dispersing

medium is discharged from the discharge outlet while the dispersing medium isseparated from the liquid containing the dispersed material. During cleaning of thestorage tank, the dispersing chamber and the conduits, the dispersing medium ispermitted to flow out of the dispersing chamber together with the cleaning fluid.
