摘要:
Washing device for one or more pleated cartridges (3) comprising a pleated filtering membrane (4) arranged around a perforated tube (5). Said washing device comprises a casing (1) which is provided with at least one discharge opening (9) and is suitable for containing said cartridges (3), as well as at least one motor (11) provided with a transmission member (13) suitable for being coupled in a removable manner with said cartridges (3) so as to rotate them around their longitudinal axis, wherein said casing (1) includes one or more nozzles (7) which are suitable for being supplied with washing liquid by at least one supply duct (8) and are turned towards the cartridges (3) for spraying the washing liquid toward the external surface of their pleated membrane (4) during the rotation imparted by said motor (11). The present invention also relates to a filter comprising said device.

摘要:
A filter module for fluids, comprising a pleated filtering membrane (6) the surface of which separates a pre-filtration volume, upstream of the filtering membrane (6), from a post-filtration volume, downstream of the filtering membrane (6), said pleated filtering membrane (6) presenting, on its surface, pleats bounded by contiguous crests (7), said filtering membrane comprising, on the pre-filtration volume side, a conveyor (10) for causing the filtrate to flow substantially between the pleats of the pleated filtering membrane (6).
摘要:
A self-cleaning filter with a permeable support (1 ) on which a filter mesh (2) is disposed, comprising a permeable protective element (3) for protecting the filter mesh (2) and disposed on it such that the filter mesh (2) is interposed between the permeable support (1 ) and the protective element (3).
