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.
