A Filter Unit, A Textile Treatment Apparatus, Use Thereof And A Method Of Filtering Microparticles

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. The second end wall is or comprises an opening therein and a removable lid, in a first configuration the opening is closed by the removable lid so that feed liquid cannot pass through the opening, in a second configuration the lid is removed from the opening so that filtered microparticles are extractable from the filter chamber through the opening. The present disclosure also relates to a textile treatment apparatus comprising the filter unit, to the use of the filter unit and the textile treatment apparatus, and to methods of filtering microparticles from feed liquid containing microparticles.
