Abstract: An apparatus for use in the treatment of substrates with a solid particulate material, said apparatus comprising: (a) a housing having mounted therein a rotatably mounted drum (8) having an inner surface and an end wall; and (b) access means for introducing said substrates into said drum, wherein said drum comprises storage means (2) for storage of said solid particulate material and a plurality of flow paths to facilitate flow of said solid particulate material between said storage means and the interior of said drum (8), characterised in that: said drum (8) comprises a dispensing flow path (5) to facilitate flow of said solid particulate material from said storage means (2) to the interior of said drum (8), and a collecting flow path (6) to facilitate flow of said particulate material from the interior of said drum (8) to said storage means (2), wherein said dispensing flow path (5) and said collecting flow path (6) are different flow paths.

Abstract: A filter unit and a filter cage, the filter unit comprising a filter chamber and a filter cage. The filter chamber comprises opposing first and second end walls, a sidewall therebetween, and an opening in the second end wall. The filter cage is rotatable in the filter unit and comprises a sidewall comprising filter media and an opening at a first end for the filter cage. The filter cage is removable via the opening in the filter chamber. The filter chamber further comprises an inlet to pass feed liquid into the filter cage via the opening and an outlet for filtered liquid. The filter unit further comprises a drive shaft to rotate the filter cage. A connection member in the filter chamber forms a rotary seal and a detachable connection to the filter cage. This arrangement permits removal and emptying of the filter cage a single operation amongst other benefits.

Abstract: A filter unit for filtering microparticles from a feed liquid containing microparticles. The filter unit comprises a filter chamber extending along an axis, and comprising opposing first end and second end walls and at least one sidewall extending therebetween and both first and second end walls are coincident with the axis. The filter unit also comprises a filter cage contained within the filter chamber and configured to rotate about the axis, the filter cage comprising one or more than one filter media for filtering microparticles from the feed liquid. The filter unit also comprises an inlet configured to pass feed liquid through the first end wall into the filter chamber. The filter unit also comprises an outlet in the filter chamber for passage of filtered liquid out of the filter chamber. The filter unit also comprises a drive shaft configured to drive rotation of the filter cage, the drive shaft extending from the first end wall of the filter chamber to the filter cage.

Abstract: The present invention relates to a filter unit suitable for filtering microfibres within a feed, especially a feed originating from a textile treatment apparatus. The present invention also relates to a textile treatment apparatus comprising said filter unit and a method of filtering utilising said filter unit.

Abstract: A microparticle filter suitable for filtering microparticles from effluent from a textile treatment apparatus. The filter comprises a filter chamber comprising chamber walls, an inlet and an outlet. The filter also comprises a filter medium contained within the filter chamber. The filter medium is configured to filter microparticles from the effluent forming a filter residue and providing a filtered effluent to the outlet. The filter comprises a filter residue collection chamber located external to the filter chamber, and a filter residue removal apparatus. The chamber walls comprise an opening and a moveable member movable between a first and a second configuration; wherein: in the first configuration the moveable member cooperates with the chamber walls to seal the filter chamber so entry of the effluent into the filter chamber is through the inlet only and exit of the filtered effluent from the filter chamber is through the outlet only.

Abstract: This invention relates to a filter which is especially for filtering microfibres which can, for example, originate from the washing of textiles. The filter is rotatable around an axis of rotation. The filter provides good filtering efficiency and improved resistance to blocking.

Abstract: A baffle for use with a treatment machine wherein the treatment machine is configured to treat substrates in the presence of solid particles and wherein the treatment machine comprises a drum and a door for loading a substrate into the drum. The baffle comprises a tub connector portion connecting the baffle to a tub of the treatment machine. The baffle also comprises a door contacting portion for contacting the door of the treatment machine when in use and the door is in a closed configuration. The baffle also comprises a barrier extending between the tub connector portion and the door contacting portion; and wherein the barrier is inclined so that when in use, solid particles deposited on the barrier are diverted into the drum of the treatment machine. There is also provided a treatment machine comprising the baffle and a method of treating a substrate in said treatment machine.

Abstract: An apparatus for use in the treatment of substrates with a solid particulate material, said apparatus comprising: (a) a housing having mounted therein a rotatably mounted drum (8) having an inner surface and an end wall; and (b) access means for introducing said substrates into said drum, wherein said drum comprises storage means (2) for storage of said solid particulate material and a plurality of flow paths to facilitate flow of said solid particulate material between said storage means and the interior of said drum (8), characterised in that: said drum (8) comprises a dispensing flow path (5) to facilitate flow of said solid particulate material from said storage means (2) to the interior of said drum (8), and a collecting flow path (6) to facilitate flow of said particulate material from the interior of said drum (8) to said storage means (2), wherein said dispensing flow path (5) and said collecting flow path (6) are different flow paths.
