Description |
Biological decolourization of two azo dye effluents (direct and
reactive dye) were investigated using a commonly available green algae
Spirogyra sp. in viable form. Batch studies revealed the potential of algal
species in removing the dye colour and dye removal was dependant on initial
algal inoculum, concentration and application class of the dye. Maximum dye
uptake was noticed on the third day for both the dyes. Higher dye uptake was
observed in the case of direct red 28 compared to reactive red 2. Dye colour
removal by the algal species may be attributed to biosorption of the dye
molecules onto the surface of algal cell and subsequent diffusion and participation
in metabolism (bioconversion). The remaining dye molecules could
be further removed from the aqueous phase by adsorption and/or chelation
reaction of the exopolymers released by the algae (biocoagulation). The results
of the present study reveal the potential nature of algae in treating azo styles .which in turn can be extended to oxidation pond system of wastewater
treatment.
