Abstract
This project concentrated on the development and subsequent results of an integrated deinking system. Although the chemistry and basic principles are quite different, a few European companies are successfully combining the two·systems by taking advantage of the differences.
Advantages of an integrated system over the conventional type included higher brightness, lower ash content and decreased sensitivity to particle size.
The experiment consisted of two different two-stage deinking systems. Each system was run twice; once with a sodium-precipitate chemistry and once with a calcium precipitate chemistry.
The system with first stage flotation, second stage washing and sodium chemistry was determined to be the most efficient.
