Deinking is the industrial process of removing printing ink from paperfibers of recycled paper to make deinked pulp. The key in the deinking process is the ability to detach ink from the fibers. This is achieved by a combination of mechanical action and chemical means. In Europe the most common process is froth flotation deinking. Inquire Now.

Significant developments related to the detachment of the toner particles from the fibers in office paper and the removal of detached ink from pulp are resulting in improved de-inking technology. Recent advances in these areas have occurred in de-inking chemicals, enzyme de-inking, agglomeration, magnetic de-inking and fundamental research on de-inking flotation by the use of atomic force.

The effect of ultrasound on the quality of recycled fibers was investigated. Ultrasound was applied to recycled pulp fiber suspension before ink removal by conventional flotation. The ultrasonic treatment induced an increase in the sedimentation volume of the fiber, which implies that the flexibility and bulkiness of the fiber increase. The water retention value of the ultrasonically treated.
