Abstract:
Apparatus for treating an aqueous working medium with at least one treatment fluid, comprising:a housing forming a treatment chamber, in which said aqueous working medium is to be treated with said at least one treatment fluid in a treatment zone,a rotatable rotor arranged in said treatment chamber to rotate about an axis, said rotatable rotor including a plurality of rotor rings carried by said rotatable rotor and coaxially arranged at the periphery of said rotatable rotor,a plurality of stationary stator rings coaxially inserted between said plurality of rotor rings, thereby forming a plurality of annular axial treatment slots having a radial size between said rotor rings and said stationary stator rings, said radial size of said annular axial treatment slots increasing with increasing distance from said axis of said rotatable rotor,inlet means for delivering said aqueous working medium and said at least one treatment fluid to one side of said annular axial treatment slots, andoutlet means for the treated aqueous working media disposed at the other side of said annular axial treatment slots,whereby said aqueous working medium is sheared in said annular axial treatment slots during operation so that a substantially homogenous shearing velocity is achieved in each of said annular axial treatment slots.
