Abstract: In a flotation system, the generated quantity of foam is determined and, independent thereof, process parameters which directly or indirectly affect the generated foam quantity are reduced in their quantity depending on foam quantity. This is brought about by reduction of specific substance flows and also such substance flows that circulate in a flotation system. Production waters used for dilution are partly replaced by fresh water. This precludes an excessive amount of generated foam from causing difficulties in the operation of a flotation system.

Abstract: A process and apparatus for preparing waste paper for reuse in a paper machine. Waste paper, water and de-inking chemicals are introduced to coarse pulping apparatus, and the coarsely pulped stock suspension is then thickened by filtration and treated in a reaction tower. The pulp is then thinned and passed through flotation apparatus to remove separated impurities, particularly printing inks. Water removed from the pulp in the thickening operation is passed through second flotation apparatus with the clean water therefrom being reintroduced to the apparatus.

Abstract: A process and plant for treating waste paper in which a beater is employed for rough-pulping the waste paper followed by a first sorting stage from which the separated-out foreign matter is processed further in a subsidiary circuit which includes a vibratory sorter for lightweight foreign matter and a hydrocyclone for heavy foreign matter, the fibers separated out during this further processing being returned again to the treatment process. In the first sorting stage, a sufficiently rigorous separation process is carried out to remove the greater part of the foreign matter, together with unpulped lumps of fibers, which is then passed to the subsidiary circuit in which it and half-stuffs still containing foreign matter, which have been sorted in the hydro-cyclone and in the vibratory sorter, are subjected together to a multi-stage further sorting and speck-removing process. The plant is characterized in that the strainer has such small holes that, in general, only pulped fibers can pass through it, and in that in the subsidiary circuit behind the vibratory sorter and the hydro-cyclone a second sorter is arranged, the half-stuff outlet duct from which opens out again in the treatment process.

Abstract: The invention concerns a process for the treatment of wastepaper, carried out for the most at a high consistency of at least 13% in the first stages, beginning the dissolution (soaking) and including a coarse sorting stage. The invention is characterized in that in the case of wastepaper containing a share of at least 40% of deinking wastepaper provided with printing inks the three first process stages, namely in this order of soaking, coarse cleaning and the further extensive dissolution of the wastepaper, take place at a considerable reduction of the wastepaper shreds to the usual speck size at a consistency of at least 13%, and the soaking under considerable addition of dissolving chemicals, and that the wastepaper including essentially all heavy contaminations, such as part of wood, glass, plastic or metal contained in the wastepaper, including pieces of metal straps of the wastepaper bales, is fed to the process.

Abstract: An apparatus for pulping paper into a pulp suspension is disclosed. A vertical container has an upper paper pulping zone and a lower pulp diluting and outlet zone beneath the pulping zone. A narrowed despecking slot communicates between the two zones. A rotor in the container circulates and breaks up the paper in the presence of the liquid in the pulping zone. Ribs on the rotor cooperate with stators in the container for defining the despecking slot. A pulp suspension dilution water inlet communicates into the dilution zone. The outlet from the container also communicates from the dilution zone. A screen protects the outlet from the dilution zone against exit of large particles therethrough and vanes on the rotor clean the screen.
