The quality of the white water in deinking mills is an often underesti
mated factor influencing the total process performance. This article d
iscusses the white water quality and its impact on deinking and bleach
ing. Ultrafiltration was used for characterization of mill white water
s and the water fractions produced were used for lab trials. Both dein
king and bleaching efficiency were affected by the water quality.
