Flotation Deinking of Recycled Paper Aided by Electric Field, 2005 Engineering, Pulping & Environmental Conference

PressWeb.jpg

Preliminary experiments suggest that electric field could enhance the efficiency of convention flotation deinking process in detaching ink from fiber surface and network. This is because physiochemical and hydrodynamic forces do not provide enough detachment force in the flotation process. Using a combined electrolytic and flotation cell has the advantage of removing the ink from both surface and network based on charge difference between ink and fiber. We study the mechanism of interaction among aforementioned forces on the ink detachment. The electric field doubled the brightness gain of flotation deinking process.
