Flotation - an overview | ScienceDirect Topics

Flotation aids are used to improve the attachment of ink particles to air bubbles. Flotation cells designs have evolved to provide such features as air injection nozzles that improve the size distribution of air bubbles. The improved brightness provides increased operating flexibility by reducing the amount of OMG that must be added to ONP.
