Abstract: Method and flotation vessel for removing contaminants from aqueous fibrous suspension. The method includes damming up fibrous suspension at a head level above a bottom of flotation vessel, and forming a bubble flow via gas bubbles rising counter to gravity in dammed fibrous suspension, such that fibrous suspension is carried counter to ascending direction of bubble flow and contaminants are deposited on gas bubbles. Accepts, discharged in cleaned form, are carried counter to bubble flow, and contaminants and bubbles are discharged in thickened flotation foam. A flow cross-section of flotation vessel transverse to bubble flow is formed straight on at least 80% of at least one side wall, and length of side wall is at least 1.5 times greater than width of end wall. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

The wet straining device comprises at least two sorting devices present in sequence, each sorting device having a wire for separating the fibrous suspension into an “accepts” portion and a “rejects” portion. The flotation device is adapted to purify the “accepts” portion of at least one sorting device, and further separates the fibrous suspension into an “accepts” portion and a “rejects” portion. The process for removing fine impurities from a fibrous suspension comprises the steps of subjecting the fibrous suspension to a dissolution process, subjecting the fibrous suspension to a pre-purification process, purifying the fibrous suspension in a wet straining process, and purifying “accepts” portions from the wet straining process by a flotation process.

Abstract: The process is designed for the flotation of interfering materials from an aqueous fibrous pulp suspension and is in particular used in the processing of printed or used paper that is otherwise contaminated. The separation of gas bubbles of the suspension occurs in a flotation layer that has a maximum thickness of approximately 100 mm. The process also achieves good flotation results in fibrous pulp suspensions that have a fiber pulp content significantly larger than 1 % by weight, for example around 2% by weight. A flotation apparatus is provided for performing the flotation process. The apparatus includes a flotation vessel, an inlet, an outlet, and a skimmer device.

Abstract: The process targets the removal of interfering materials from an aqueous fibrous material suspension, especially if this is produced from recycled paper. Thereby interfering materials, such as printing ink particles, small synthetic particles, or sticky contamination, are eliminated by flotation in a particularly advantageous manner. In accordance with the invention, the combination of low-intensity and high-intensity flotation is undertaken, whereby the low-intensity flotation generally works in the gravitational field and the high-intensity flotation in a centrifugal field.

Abstract: A process and apparatus serves to remove solid matter from an aqueous material suspension produced from printed used paper. As many interfering material particles are collected by floatation as possible in a floatation foam and diverted as a reject. A perforated separating element is located above the fibrous material suspension. Between the separating element and the floatation foam, an intermediate layer is formed. In the intermediate layer the fibers, which have been entrained by gas bubbles are again rinsed and retrieved.
