A 10-day mill trial of near-neutral sulphite deinking. Part III: Mill assessment

In this third part of a three-part series on a 10-day mill trial of near-neutral sulphite deinking, we report data collected from outside the recycle plant. The following observations were made: There was better runnability on paper machine #5 which correlated with a lower deposition rate index as measured on the paper machine rich white water. During the entire trial, paper machine #5 ran with 34% DIP. This extended production at 34% DIP with …
