Abstract: Verfahren zur Filtration und Entwässerung von Klärschlämmen (1) in einer Membranfilterpresse (9), bei dem Klärschlamm (1), gegebenenfalls mit Zuschlagstoffen (2), wie Kohle oder Asche, unter Zugabe eines Flockungshilfsmittels, zB einem organischen Polymer, in einem Kontaktwerk (3) vermischt und geflockt und über eine Pumpe (4) der Membranfilterpresse (9) zugeführt wird, dadurch gekennzeichnet, daß der, gegebenenfalls mit Zuschlagstoffen (2), versetzte Klärschlamm (1) über eine Leitung (5) einem Zylinderrührer (7) mit rotierenden, im Durchmesser über die Zylinderlänge veränderten Zylinderdurchmessern, vorzugsweise mit abgestuften Zylindern (7a, 7b, 7c), zugeführt wird, das Flockungshilfsmittel über eine Leitung (6) in den Zylinderrührer (7) eingeführt wird, daß unter angepaßten Schergefällen bzw. Energieeinträgen zunächst der gegebenenfalls mit Zuschlagstoffen (2) versetzte Klärschlamm (1) und das Flockungshilfsmittel im ersten Bereich (7a) intensiv durchmischt, dann im Zylinder mit einem geringeren Durchmesser (7b) gezielt die Flocke aufgebaut und die Flocke abschließend, im Bereich des letzten Zylinders (7c), mechanisch stabilisiert, und der so geflockte Klärschlamm (1) über eine Ableitung (8) der Membranfilterpresse (9) zugeführt wird.

Abstract: The invention relates to a method for producing agglomerates comprising a core-shell structure in which: i) primary agglomerates are prepared that contain a first particle-shaped solid; ii) a second particle-shaped solid is agglomerated in the presence of the primary agglomerates while adding a binding liquid in order to obtain agglomerates of the second stage, and optionally; iii) an nth (n>/=3) solid is agglomerated in the presence of the agglomerates of the (n-1)th stage while adding a binding liquid in order to obtain agglomerates of the nth stage.

Abstract: The present invention relates to a continuous process for producing ferti lizer granules. The process is particularly suitable for producing fine-part icle fertilizer granules. The fertilizer granules are produced in a mixer ha ving a horizontal cylindrical mixing chamber and a fast-rotating shaft that is centrically arranged in said mixing chamber and that is equipped with mix ing tools. The invention further relates to the granulated fertilizers obtai nable by this process, and to the use thereof for fertilizing agricultural a nd/or horticultural crops.

Abstract: A process for producing agglomerates with a core/shell structure, in which i) initial agglomerates containing a first particulate solid are prepared; ii) a second particulate solid is agglomerated in the presence of the initial agglomerates with the addition of a binder liquid to give second stage agglomerates and, where appropriate, iii) an nth (n>=3) solid is agglomerated in the presence of the (n-1)th stage agglomerates with the addition of a binder liquid to give nth stage agglomerates.

Abstract: Filtration and dewatering process is as follows. Sludge (1) is opt. mixed with additives such as coal or ash (2) in a contact device (3). The sludge and additives (1,2) are sent by a pump (4) along a line (5) to a cylindrical stirrer (7) with a rotating cylinders (7a,7b,7c) along the length of the cylinder, where the cylinders have changing dia. (pref. with the dia. changing in steps). A flocculating agent such as an organic polymer is supplied at an inlet (6). Rotational energy input sets up shear force gradients, promoting intensive mixing in the first section (7a), flock formation in the second (7b), and mechanical stabilisation of the flocks, in the third (7c). The flocculated mixt. is sent by a line (8) to the filter press (9). Also claimed is a cylinder stirrer as described above for stirring, mixing, agglomerating or flocculating two or more components, such as sludge.
