Colour removal from complex effluents is a matter of concern pertaining to the
toxicity, visibility problem and its acceptance for reuse. Various physical and
chemical methods including adsorption, ion exchange, filtration and coagulation
are commonly used for removal of colour from effluent streams. Adsorption is
more common because of its easy operation and availability of variety of
adsorbing media. The only disadvantage with this process is that once exhausted,
the adsorbing media needs replacement which imposes a recurring cost on
operator. As a result, applicability of a bio-adsorbent (made from sugarcane
baggase) was tested for removal of colour from effluent which not only appears
as a low cost adsorbent but also provides solution to the problem of unmanaged
baggase produced from sugar factories. The adsorption capacity of this
bio-adsorbent was checked at various flowrate at a specific column height. The
effects of contact time on reduction in colour were also examined at batch
scale. The colour removal efficiency in most of the experimental trial was
observed as higher than 90% which shows that baggase from sugar industry can be
a potential replacement of conventional adsorbents.
