The deinking through flotation separation process is not 100% efficient, and its efficiency can be calculated by using a feed sample (pulped but no flotation) as comparison. It is also important to understand the tradeoff between fiber yield and cleanliness efficiency. Generally,
MAK-C™ Flotation Cell for Deinking. Based on more than three decades of Kadant innovation and expertise in advanced flotation technology, the MAK-C compact flotation cell offers maximum yield and efficiency. The operating principle is based on the combined multi-stage effect of our unique tank flotation and column flotation using different

The MAC flotation cell is mainly used in the flotation section of waste paper deinking pulping, for removal of hydrophobic impurities such as filler, ash, ink particles, etc. It can increase pulp whiteness and meet the requirements of final paper appearance quality. Table 11.11 shows the features of MAC flotation cell.
Commercial flotation deinking cells cover a great range of air flow rates (from 20% up to 1000%) but most units operate at a rate below 100%. low sludge generation and the high efficiency of
Froth flotation efficiency is determined by a series of These forces are complex and vary within the cell. High shear will be experienced close to the impeller of a mechanical flotation cell and mostly gravitational force in the collection and cleaning zone of a flotation column. flotation columns, Jameson Cells or deinking flotation
The efficiency of a flotation cell (with respect to ink removal and process yield) is very sensitive to the surfactant chemistry utilized. The tested natural surfactants based on sugar components have high efficiency relative to synthetic (petroleum-based) surfactants in flotation deinking.
from flotation cells. Surfactants can affect these subprocesses either positively or negatively. To understand how a surfactant can positively and negatively affect the flotation deinking process, the basic chemistry of surfactant in solution should be discussed.
