Deinking Process Water Flotation: an Innovative Solution

Floating process water with adapted technology is an efficient way to decrease SAS concentration and therefore recover flotation deinking selectivity This concept was tested at industrial scale with success: first loop clear filtrates of a deinked pulp line (for newsprint production) were floated.

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.

Paper recycling

The industrial process of removing printing ink from paper fibres of recycled paper to make deinked pulp is called deinking, an invention of the German jurist Justus Claproth Contents Methods The process of waste paper recycling most often involves mixing used/old paper with water and chemicals to break it down It is then chopped up and.
