    Abstract: A pulp-filter arrangement (1) comprises a rotatable drum (10) and a non-rotating valve arrangement (30). The rotatable drum (10) has a cylindrical water-permeable pulp-supporting shell (14), a plurality of drain pipes (16) and a rotating hollow shaft (18). The plurality of drainpipes (16) connects the rotating hollow shaft (18) with a collecting channel (22) situated radially directly inside the cylindrical water-permeable pulp-supporting shell (14). The non-rotating valve arrangement (30) is disposed within the rotating hollow shaft (18) for sealing off the rotating hollow shaft (18) from a radially inner outlet (24) of the drain pipes (16) when respective radially inner outlet (24) is situated within a sealed zone. The non-rotating valve arrangement (30) is further arranged to, in a transition zone immediately following the sealed zone, open a throttled passage between the rotating hollow shaft (18) and the radially inner outlet (24).

    Abstract: An adjustable vacuum pan assembly [190] for a belt filter [900] is disclosed. The adjustable vacuum pan assembly [190] comprises an arm [140] configured to be attached to a frame portion [930] of the filter [900], a vacuum pan [150] adjustably connected to the arm [140], and a cam [170] operatively coupled to the arm [140]. The cam [170] is rotatable with respect to the arm [140] and has a peripheral surface which contacts a portion [157] of the vacuum pan [150]. The assembly [190] further comprises a locking member [169] which serves to hold the cam [170] against rotation with respect to the arm [140]. Varying an angular rotational position of the cam [170] effectively varies a spacing between the vacuum pan [150] and the arm [140], thereby providing an amount of misalignment compensation therebetween. Retrofit kits for a preexisting conventional filter [900] and methods of providing increased adjustability to a filter [900] are also disclosed.

    Abstract: A method of separating a mixture of liquid and insoluble solids in a filter press may comprise: diluting the mixture; adding a flocculating agent to the diluted mixture and stirring to form a chemically processed mixture; pumping the chemically processed mixture into a chamber between two filter plates in the filter press to form a filter cake, wherein the chamber is lined by filter cloths, and wherein, during the pumping, filtrate is forced through the filter cloths and out of the chamber; heating the filter cake in the chamber, wherein, during the heating, filtrate is forced through the filter cloths and out of the chamber; and releasing dried filter cake from the chamber. During the heating, the chamber may be vacuum pumped to facilitate removal of water vapor. Furthermore, before the diluting, additional solids may be added to the mixture. The method may be used to dewater drilling mud, and mixtures of drilling mud with drill cuttings. A system for dewatering a mixture of drilling mud and drill cuttings may comprise: a mixing vessel for mixing together the drilling mud and drill cuttings to form the mixture; a filter press for dewatering the chemically processed mixture; a pump for pumping the mixture from the mixing vessel into the filter press; and a heater for heating the mixture in the filter press.
