摘要： A system and method are provided for producing from a first fluid having particles of a substance suspended or dissolved therein with a first concentration of the substance, a second fluid having a second concentration of the substance lower than the first concentration and a separated-fluid product, in which concentration of the substance is greater than that in the first fluid. The system comprises a pre-treatment module for processing the first fluid to produce aggregates from the substance and at least one separation duct in fluid communication with an outlet of the pre-treatment module, the duct having at least one bay portion having such design as to cause aggregates to accumulate along a pre-determined wall of the bay portion, thereby facilitating separation between the second fluid and the separated-fluid product.

摘要： A filter includes a filter assembly deployed within a pressure vessel. The filter includes a series of filter configurations arranged along a central flow path connected to an outlet. Each filter configuration has filter screens overlying at least one filtrate channel which directs filtered fluid to the central flow path, A partition is deployed within the pressure vessel so as to subdivide the pressure vessel into a first filter chamber and a second filter chamber, each containing a number of the filter assemblies. A flow diverter is deployed in the central flow path for diverting a flow of filtered liquid passing along the central flow path from the first filter chamber so as to flow outwards from the central flow path to undergo a second filtering in the second filter chamber. Also disclosed is an outlet flow throttling arrangement to avoid overload of a backwash cleaning system.

摘要： A filter filters a flow of liquid and has a pressure vessel, a filter assembly deployed within the pressure vessel, and a backwash assembly. The pressure vessel has an inlet, an outlet, and a flow path in fluid communication with the outlet. The filter assembly has at least one filter unit and at least one support configuration that supports the at least one filter element. The at least one filter element has first and second coarse mesh material support layer that have apertures of a first and second size, respectively, and a cloth filter layer that has apertures of a third size smaller than the first and second sizes. The cloth filter layer is interposed between the first and second coarse mesh material support layers. The backwash assembly has a suction nozzle in facing relation to a first or second surface of the filter unit.

摘要： A filter for filtering a flow of liquid a filter assembly with a number of filter disks coaxially arrayed along a central flow path within a pressure vessel. Each filter disk has a number of segments. The segments are preferably implemented as spacers with outward-facing filler screen support configurations supporting first and second filter screens. The filter screen support configurations have a cellular form that is open over a majority of a surface area, An arrangement of support ribs are deployed to maintain a spacing between the first and second filter screen support configurations. At least 80 percent of an internal volume of each of the segments is preferably open to allow liquid flow from the screens to the central flow path. Also disclosed are modular structure's of the filter disks, and a backwash arrangement which performs a spiral scanning motion across the surface of each filter disk.
