摘要
The process for de-inking paper, comprises eliminating ink particles by flotation, separating surfactants by dispersed air flotation (22), and eliminating flotation foams (6) containing the separated surfactants. The separation of the surfactants is carried out in waters of a first flotation loop and a clear filtrate filter disk (8) or in thickened water of the flotation foams. The flotation foams are treated with ozone and then evacuated at a level of sludge drainage unit. An independent claim is included for a device for de-inking paper.
