S. Veilleux et al., Quantification of macro stickies and optimization of the wastepaper deinking process - A method applied to a Bowater mill decreased stickies by 38%, PULP PAPER, 101(12), 2000, pp. 130-133
The control of macro stickies at Bowater Pulp and Paper Canada is discussed
. A method has been developed as a quality control measure for deinking ope
ration. A Sommerville six-cut screen uas used to concentrate macro stickies
in screen rejects followed by quantification by image analysis. Trials car
ried out with mill's pulp samples showed that the method has a good reprodu
cibility. The methodology was used to optimize fine screens and Gyrocleaner
s. Process optimizations decreased the over-all macro stickies level in the
deinked pulp hy more than 38%.
