摘要： Ein Verfahren zur Fest-Flüssig-Trennung von Suspensionen, insbesondere von Klärschlamm (K), arbeitet unter Zugabe von Flockungsmitteln (F1) und/oder Flockungshilfsmitteln. Mittels eines Sensors (S1) wird die Suspension, insbesondere der Klärschlamm (K), betrachtet. In einem ersten Verfahrensschritt erfolgt die Zugabe von Flockungsmitteln (F1) und/oder Flockungshilfsmitteln in eine erste Mischstufe (M1), bis mittels des Sensors (S1) die Bildung erster Flocken festgestellt wird. Die Zugabe des Flockungsmittels (F1) und/oder des Flockungshilfsmittels wird dann unterbrochen, so dass die Suspension, insbesondere der Klärschlamm (K), in diesem Moment einen definierten, nämlich gerade erste Flockenaufweisenden Zustand aufweist. Die Suspension, insbesondere der Klärschlamm (K), wird nun einer weiteren Mischstufe (M2, MM) zugeführt. In dieser weiteren Mischstufe (M2, MM) wird das gleiche (F1) oder ein anderes (F2, F3) Flockungsmittel oder Flockungshilfsmittel in einer Menge zugesetzt, die vorbestimmt ist und ausgehend von dem definierten Zustand der Suspension, insbesondere des Klärschlamms (K) einen gewünschten Anteil an Flocken in der Suspension, insbesondere dem Klärschlamm (K) herbeiführt. Die entstehende Mischung wird dann mittelbar oder unmittelbar einer Fest-Flüssig-Trennung zugeführt.

摘要： A method for controlling the operation of a continuously or periodically operating centrifuge can be employed in the sugar industry for separating crystalline carbohydrates or sugar alcohols from a crystal suspension called a magma or a mother liquor. The magma has a varying content of fine grain that is dependent on the properties of the pretreatment and of the raw material. Variable control values are provided in a control device of the centrifuge. One or plurality of sensors are provided that carry out the measurements in electromagnetic, optical, acoustic, and/or conductive ways. These measurements that are conducted serve for determining the fine grain fraction of the magma. The measurements are supplied as measurement signals to the control device of the centrifuge. The control device automatically analyzes the measurement signals supplied to it and evaluates them with respect to the fine grain content of the magma. The control device changes the variable control values of the centrifuge as a function of this evaluation.
