Controlling Contaminants in the Production and Use of Deinked Pulp
نویسنده
چکیده
Recycled fiber use introduces fines, fillers, microbiological contaminants and stickies contaminants to the papermaking system. Deinking processes are designed to remove or control these contaminants. Important considerations in selecting a deinking processes are the type of wastepaper to be deinked and the desired quality of the deinked pulp. These will determine the extent to which contaminants must be removed and controlled. An understanding of the behavior of contaminants across each unit operation and the role of surface chemistry is improving removal efficiency is essential for effective control.

Control of Sticky Contaminants with Cationic Talc in Deinked Pulp
In this study a cationic talc was applied to deinked pulp for control of sticky contaminants. Effects of the cationic talc on stickies and dissolved and colloid substances were investigated and compared with those of a conventional talc. Characteristics of wet-end chemistry were examined for the pulp with addition of both kinds of talc samples. Furthermore, influences on paper properties were a...
متن کاملUse of Enzymes in Deinked Pulp Bleaching
To comply with government’s environmental policies and to satisfy the requests of the consumers, recycling of waste paper is essential for reducing the consumption of virgin fibers in pulp and paper industry. However, the poor optical properties of recycled fibers restrict their use in value-added papers. Enzymes, such as lipase and laccase, represent an interesting alternative. The detachment ...
متن کاملA Bubble Detection Algorithm based on Sparse and Redundant Image Processing
Abstract Deinked pulp flotation column has been applied in wastepaper recycling. Bubble size in deinked pulp flotation column is very important during the flotation process. In this paper, bubble images of deinked pulp flotation column were first caught by digital camera, and then the bubbles were detected by using a detection algorithm based on sparse and redundant image processing. The result...
متن کاملWaste management from pulp and paper production in the European Union.
Eleven million tonnes of waste are produced yearly by the European pulp and paper industry, of which 70% originates from the production of deinked recycled paper. Wastes are very diverse in composition and consist of rejects, different types of sludges and ashes in mills having on-site incineration treatment. The production of pulp and paper from virgin pulp generates less waste but the waste h...
متن کاملTime Variations of Macrostickies and Extractable Stickies Concentrations in Deinking
The stickies content, both macrostickies and stickies extractable in a solvent, was determined for samples taken at short time intervals from deinking lines, producing deinked pulp for newsprint production. The study was carried out at three mills on different continents, with each having a different source of recycled paper as raw material. The short-term variations in extractable stickies in ...
