Process Variables That Affect Deinking Operations and Final Deinked Pulp (DIP) Quality, 1995 Engineering Conference Proceedings

Lowell F. Lott

Christopher D. Perry

Standard and ideal processes are illustrated that are essential for the production of quality or market acceptable deinked pulp. Cleaning, screening, ink flotation, ink washing, brightening, and process water clarification variables are listed and discussed. The impact that furnish consistency has on final deinked pulp is illustrated for three defined secondary fiber types. Finally, problems that result from poor process control and a misunderstanding of water quality and secondary fiber quality prior to the deinking process are tabulated and reviewed so that a process trouble shooting checklist can be constructed.
