Plant Layout and Deink Method

The present invention relates to a method and layout for waste paper treatment having at least two de-ink circulations connected in series， wherein at least one pre-flotation， disperser， and second circulation in the first circulation Inner， has a post-flotation connected after the disperser. By the post-flotation fractionation， the effluent fraction with dispersed ink， filler， particulates and fibers is separated. According to the present invention， the at least one partial stream of the after-floating sorter effluent is preceded by the pre-floating sorter of the preceding first circulation section or conveyed to the pre-floating sorter， or to the floating sorting section of the parallel de-inking line. Is returned. The invention concerns a layout and a method for the processing of paper wastes， with at least two deinking circuits connected in series， having at least one preflotation in a first circuit， a disperser and a postflotation connected after the disperser in a second circuit. By means of the postflotation， a reject fraction with dispersed ink， fillers， fines and fiber is separated. According to the invention， at least one partial stream of rejects of the postflotation is returned to the preceding first circuit， prior to or in the preflotation or a flotation of a parallel deinking line.
