Abstract: A system and method for refurbishing filter plate assemblies of an industrial horizontal filter press is disclosed. The system may comprise multiple stations and the method may comprise one or more process steps associated with each of the stations. A station may ready the plate assemblies, provide for checking the function of spray nozzles, provide for the removal of filter cloths and/or feed eye grommets, or provide for the washing of plates. A final station may be used for final assembly and inspection. A rework station may be provided to hold filter plate assemblies which are not suitable to return to service in the industrial horizontal filter press. Stations may perform single operations, or they may be equipped for performing multiple operations at once, without limitation.

Abstract: The disclosure relates to a method of controlling a filtration process using a filter (5), and further relates to a filtration system (1). The method employs predictive and/or adaptive learning protocols to initialize and reinitialize control set points for filtration parameters of a filter (5) over time. Inputs (11) are received by an operating algorithm (10) and are processed to deliver a number of outputs (12) including instructions which may include the adjustment of one or more control set points which affect the operation and/or performance of the filter (5). The control set points may be altered, in response to changing inputs (11), in order to achieve the most efficient run settings for a filter (5), whilst still maintaining or exceeding target cake product (60, 61) specifications.

Abstract: A method for pre-coating filter media of a filter (108) may comprise the step of performing a separation on a first portion of slurry (102) to be dewatered by the filter (108). A coarse stream (102c) may be produced from the separation and at least a portion of the coarse stream (102c) may be provided to the filter (108) to pre-coat the filter media of the filter (108). The coarse stream (102c) or a refined coarse stream (102f) may be provided to the filter (108) before providing a second portion of the slurry (102) to the filter (108). Filtration systems (101) and methods may allow pre-coating techniques without necessarily using a consumable pre-coat media (e.g., diatomaceous earth).

Abstract: An overpressure valve (1) is disclosed. The overpressure valve (1) is configured as a drain valve assembly (1) for a filter plate (7) within a horizontal filter press. The overpressure valve (1) has a plug (5) provided with an upper collar (5a), a pressure surface (5d), a sealing surface (5e) below the pressure surface (5d), and a plurality of elastomeric webs (5b) extending between the upper collar (5a) and the pressure surface (5d). The webs (5b) are configured to elastically deform or temporarily stretch when the pressure surface (5d) is exposed to pressure and are preferably non-metallic to improve wear performance from abrasion and/or corrosion.

Abstract: A filter cake analyser (1) is disclosed. The analyser (1) may include a probe (7) configured to extend into a path of filter cake (6) (or other material) and convey a sample amount of filter cake (6) from a catch basin (9) to a probe discharge (11). 5 A sample cup (17) of an indexable cup assembly (16) is filled with the sample amount of filter cake (6). A rotational actuator (22) supporting the cup assembly (16) indexes the cup assembly (16) between three cup assembly positions. A dryer (15) of the filter cake analyser (1) dries the contents of the sample cup (17), and a load cell (28) intermittently engages and disengages with the cup assembly (16) 0 via an actuator (26) to obtain dry and wet mass measurement values to calculate moisture content of the sample amount of filter cake (6).

Abstract: A filter cloth (1) for an industrial filtration device may comprise a thin porous sheet of filtering material (4) and one or more conductive elements (3). The one or more conductive elements (3) may be provided in the form of a filament or thread comprised of electrically-insulated conductive material. The filament or thread may form a portion of an RFID antennae, a series circuit, and/or a parallel circuit. When abrasive particles cause the filament or thread to be compromised or destroyed, a response signal may be generated providing an indication that the filter cloth (1) is in need of repair or replacement.
