Flotation Deinking Paper Recycling De-Inking Waste Paper

The pulping consisted of disintegration of the wastepaper structure and dispersion of the fibers. The disintegration was accomplished by conditioning 250 grams of wastepaper, under moderate agitation, with hot steam (84 to 90 °C), de-ionized water and reagent as desired. After disintegration the pulp was further dispersed in a high speed blender. All pulping experiments were done at a

Application of Hydrodynamics in Design of Flotation

Recovery and recycling of waste paper has become increasingly important with demand for paper products sharply growing. The flotation process is the predominant technology for the removal of inks from waste paper because of its advantages. Flotation cells may be very different in size and shape, but the key elements ensuring aeration, ink collection and bubble separation are always present.

Semi-Empirical Modelling and Management of Flotation

Particle transport in flotation deinking cells can be modelled using semi-empirical equations accounting for four main transport phenomena, namely, hydrophobic particle flotation, entrainment and particle/water drainage in the froth (Beneventi et al., 2006). 2.1. Flotation.
