Assessment of Phycoremediation Efficiency of Spirogyra Sp. Using Sugar Mill Effluent

Abstract:
Phycoremediation is the use of algae for the removal of pollutants from wastewater since algal species are relatively easy to grow, adapt and manipulate within a laboratory setting and appear to be ideal organisms for use in remediation studies. The present investigation was carried out to determine the phycoremediation potential of Spirogyra sp. using sugar mill effluent. The results of the present study revealed that sugar mill effluent is considerable loaded with TDS, EC, BOD, COD, TKN, PO43- , Ni, Cr, Fe and Mn. The phycoremediation studies showed that the maximum removal of TDS (24.92%), EC (14.47%), pH (11.47%), BOD (47.82%), DO (21.46%), COD (15.73%), TKN (40%), PO43- (44.44%), Ni (42.79%), Cr (40.74%), Fe (24.78%) and Mn (34.92%) was recorded after 60 days of phycoremediation experiments using Spirogyra sp. moreover, the removal of TDS, EC, BOD, COD, TKN, PO43- , Ni, Cr, Fe and Mn of the sugar mill effluent was progressively increased at 15, 30, 45 and 60 days of phycoremediation experiments using Spirogyra sp. Therefore, the phycoremediation study clearly indicated the effectiveness of microalgae Spirogyra sp. for the removal of nutrients and heavy metals present in the sugar mill effluent.
