Abstract

The Objective of the current study was to evaluate the water quality of textile effluents collected from three distinct zones in the Jaipur region of Rajasthan, India, viz. Sitapura, Sanganer, and Bagru. Results show high pH (8.62), TDS (73003mgL-1), BOD (70.66mgL-1), and COD (2851.9mgL-1) levels including metals Cr (2.5mgL-1), Cu (2.46mgL-1), Zn (2.13mgL-1), Mn (1.63mgL-1), and Cd (2.06mgL-1). For the phytoremediation study, fresh plants of Eichhorniacrassipes, Pistiastratiotes, and Spirodelapolyrhizacollected from the Dravyavati River, acclimatized, and grownat different concentrationsof textile effluent (5%, 10%, and 15%)in lab condition with a set of control plants for 15 days.The phytoremediation efficiency of selected plants was assessed during the entire experiment duration and observed that Eichhornia crassipesefficiently reduced BOD (32.81%), COD (40.44%), total suspended solids (28.94%), and total dissolved solids (21.82%) including metals (Cr (29.87%), Co (20.94%), Zn (25.78%), and Cd (26.19%) grown in 15% of textile effluent.Results indicate that Eichhornia crassipesemerged as an efficient phytoremediator plant for the treatment of textile effluents as compared to Pistiastratiotes, and Spirodelapolyrhiza, however, employing allthree aquatic plants in combination could be more effective for developing biological wastewater treatment system for environmental protection and management.
