Electrohydraulic Contaminant Removal

Adhesive materials, also called stickies, on secondary fiber feedstock can degrade the quality of recycled paper products and therefore need to be removed. Electrohydraulic contaminant removal is a new technology which uses the discharge of sparks in cleaning and screening processes to enhance the removal efficiency of stickies and to increase the efficiency of floatation de-inking. The technology is tested in several mills, resulting in improved stickies removal, floatation, and clarification efficiencies. These could lead to improved energy efficiency.
