The invention relates to a device for separating a first substance from a flowable primary substance flow, to a control unit, to a machine-readable program code, to a storage medium, and to a method for separating a first substance (S1) from a flowable primary substance flow (P) by means of a separating device (1), wherein the method comprises a mixing step and a precipitation step, wherein by means of the mixing step the first substance (S1) and at least one magnetic carrier particle (M) are bound to each other, wherein by means of the precipitation step the carrier particles (M) contained in the primary substance flow (P), including the bound first substance (S1), are separated by means of magnetic forces into a residual primary substance flow (R) depleted of the first substance (S1) and a secondary substance flow (S) enriched with the first substance (S1). The economic efficiency and environmental compatibility can be considerably increased by varying a parameter, which influences the magnetic forces, in a predetermined manner during the precipitation such that the content (G) of the first substance (S1) in the secondary substance flow (S) and/or in the residual primary substance flow (R) is influenced by said variation, wherein the change of the content (G) of the first substance (S1) in the secondary substance flow (S) or in the residual primary flow (R) caused by the variation is determined and, on the basis of the change of the content (G) depending on the predetermined variation, at least one parameter of the separation method is set. |
