Abstract: A transportable plant for processing a slurry by means of a chamber filter press designed as a membrane press contains at the same time a feed system for producing the slurry and diverse machinery for influencing temperature and pressure in the interior of the chamber filter press, such as a superheated steam unit, a hot air unit and a vacuum plant, which can be connected to the interior of the plant via switchable or controllable valves. The plant is suitable particularly for producing materials which are flowable or are in pieces, for example colorants, soup and drink powders, vegetable snacks and fruit snacks and diverse pharmaceuticals and for processing sewage sludge by filtration and subsequent drying or freeze-drying of the filter cake in the chamber filter press.

Abstract: Apparatus for draining of muddy liquids, especially of sludges and slurries in sewage clarification plants, where first of all an ionic coagulant, eg., an anionic or cationic coagulating agent, is added to the muddy liquid in a first ionic coagulating means to obtain an aqueous sludge which is separated from the muddy liquid in a first coagulating chamber by sedimentation in a straining zone and wherein the aqueous sludge is subsequently filtered and pressed, whereafter the liquid is treated in a second coagulating or mixing chamber.The apparatus to carry out the process comprises in addition to the first coagulation chamber coagulation chamber for the muddy liquid, a revolving screening belt constituting the filtering means for the straining zone and a series connected revolving screen belt press which aids in dewatering the filtered solids.
