| Abstract: | The paper industry
requires large volumes of process water of high purity and generate equally
large volumes of waste water from digestion process, which is highly coloured.
The removal of colour from paper mill waste water is one of the major
environmental problems, because of the difficulty of treating such water by
conventional methods. The present study was undertaken for removal of colour
from paper mill effluents using waste sludge from ETP as an adsorbent, with
heat treatment. The operating variables studied were effluent concentration,
adsorbent dosage and contact time. |
