After chemical or enzymatic treatment of pulp, flotation was performed using Voith Delta 25™ laboratory flotation cell with a cell capacity of 23.6 L. Pulp slurries diluted at 1.0% consistency were subjected to pre-mixing for 5 s without air flow ensuring the mixing of surfactant throughout the pulp suspension.
Single-stage flotation lines simulated in this study. (a) Simple line made of a series of n flotation cells. (b) Line with n flotation cells with the reject of the last n - m cells cascaded back at the line inlet. (c) Line composed by n flotation cells with the first two cells in parallel and the remaining cells in series.

The collapsed and condensed liquid from the flotation deinking cell amounting to 7.3 tonne/day and 173 L/min was disposed of as waste [3], while the flotation effluent [4] was discharged to two inexpensive thickeners for thickening of pulp in a …
The pulp is poured into the cell and the concentrate overflows the lip, while the pulp that remains after a determined flotation time represents the tailings. More importantly, these laboratory machines are designed for batch testing, meaning that steady state cannot be reached.
The right amount of air, together with the optimized injector geometry lead to optimum bubble size distribution − the key to excellent deinking performance. Superior flow …
The techniques used for the production of deinked pulp are completely different than those used for the production of pulp from wood. The recycling technology is the combination of the various treatments performed to produce a pulp from recovered papers and to clean it for its use on a paper machine to produce paper.
The flotation machine must perform a series of complicated functions. Some of the more obvious are: 1. Good mixing of pulp. To be effective, a flotation machine should maintain all particles uniformly in suspension within the pulp, including those of relatively high density and/or size.
High and uncontrolled surface active substances (SAS) concentrations in deinking line process waters strongly disturb flotation deinking. Indeed, their adsorption at air/water and ink/water interfaces stabilizes air bubbles and ink particles,
Efficient Paper Pulp Deinking Flotation Machine. Efficient deinking effect requires fulfilling two requirements: increasing brightness of paper sheet as much as possible while at the same time retaining as many fibers as possible.Leizhan flotation deinking machine can meet the two requirements.
Abitibi-Consolidated operates six (6) waste paper deinking plants for the production of newsprint, using a variety of process designs and flotation cells. A study comparing the results of each plant's deinking system performance identified differences in flotation cell operating conditions [1], the effects of which were not well understood.
