摘要： A process (1, 101, 201) for separating a fibrous target component (21) from textile waste (2, 5) is shown, said textile waste (2, 5) containing the target component (21) and at least one ancillary component (22), whereby the target component (21) consists of water-swellable textile fibers (51) with a density higher than the density of water, the process (1, 101, 201) comprising the steps: a) dispersing the comminuted textile waste (5) in an aqueous solution (7) to obtain a suspension (8) containing the textile waste (5), and b) separating the dispersed textile waste (5) into a high-density target fraction (81) comprising the target component (21), and a low-density residual fraction (82) comprising the at least one ancillary component (22), according to the respective density of said components (21, 22). In order to provide a reliable, fast process for the separation of water-swellable fibers from other textile fibers which are similar in density, it is proposed, that the aqueous solution (7) is an alkaline aqueous solution (7) and the target component fibers (51) are swelled in the alkaline aqueous solution (7) prior to step b), thereby increasing the density and weight of said target component (21) relative to the density and weight of the ancillary component (22).

摘要： The invention relates to a process for filtration of fluids, especially of aqueous media, by means of a backflush filter apparatus consisting of a cylindrical housing, a cylindrical and perforated support body installed coaxially therein, a filter material, a support fabric, and a mobile backflush device present therein, said process enabling improved removal of fine and ultrafine particles, and of particles with greasy or compressible consistency, and allowing higher solid concentrations. The process according to the invention has the steps below. a) Formation of a filtercake in the perforation of the support body; b) deposition of the relatively fine particles or of the particles with greasy or compressible consistency on or in the filtercake; c) backflushing after attainment of the predefined filter loading or of the maximum permissible pressure differential, or when the filtrate volume flow goes below a minimum. A further aspect of the invention is a filter apparatus for performance of the process, characterized in that the filter material consists of a filter fabric with an air permeability of 700-1300 l/m2s at pressure differential 200 Pa.
