    Abstract: A filter (20) configured to separate the solid components and the liquid components from a slurry. The filter (20) includes a plurality of filter plate assemblies (46) that cooperate to define a plurality of filter chambers (70), each defining a perimeter (96) having an open section (98) when the filter plates (68) are in a closed position relative to one another. Each filter plate assembly (46) includes a closure (104) configured to close the open section. Preferably, the closures (104) are movable to an open position to permit a particulate cake to be removed from the filter chambers (70) without separating the filter plates (68).

  • Patent number: 8535542
    Abstract: A method of separating a mixture of liquid and insoluble solids in a filter press may comprise: pumping the 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 wherein the heating is by radio frequency irradiation of the filter cake in the chamber; and releasing dried filter cake from the chamber.

  • Patent number: 8480891
    Abstract: Apparatuses and methods for making and using a filter cloth assembly are described. A filter cloth assembly can have a liquid permeable filtering media attached to a connector ring. The liquid permeable filtering media separates at least one solid from at least one liquid in a slurry. The filtering media has a feed hole formed therein to allows passage of a slurry through the filtering media. The connector ring includes a flange having an upper flange section and a lower flange section. The lower flange section receives an edge of the feed hole to connect the filtering media to the connector ring such that the face of the filtering media is substantially flush with the upper flange section.

  • Patent number: 8317992
    Abstract: The present disclosure is directed at a modular apparatus for a saltwater desalinating system, and a method for using same. The apparatus includes multiple internal modules that are compressively coupled to each other. Each of the internal modules includes a pair of rigid end plates located at opposing ends of the internal module, and a stack of membrane bounded compartments that are layered from one of the end plates to the other. The modular apparatus can be used in a membrane based desalination system, which includes concentration difference energy systems, electrodialysis reversal systems, and membrane distillation systems. The modular apparatus helps to mitigate problems such as leakage and buckling in such systems, and can be used to increase membrane packing density and, accordingly, desalination efficiency.

  • Patent number: 8313645
    Abstract: The invention relates to a filter device comprising at least one filter chamber (7) configured between a chamber side (5) and a membrane side (6) of two parallel filter plates (1) and divided through two filter cloths (4), the membrane sides (6) of the two filter plates (1) each comprising a membrane (3), an outlet (8), and a deviation element (12) attached to the outlet (8) and penetrating the membrane (3). When the filter device is closed, a suspension containing a solid substance can be inducted between the filter cloths (4) in such a way that a filtrate penetrates the filter cloths (4) on the chamber side (5) and on the membrane side (6), while the solid substance is deposited in a filter cake on the filter cloths (4). The filtrate flows initially substantially parallel to the filter cloth (4) towards the outlet (8), is deviated through the deviation element (12) in an outlet direction (9) perpendicular to the filter cloth (4), and flows out through the outlet (8).
