Abstract
Textile industry has posed serious environmental problems causing adverse health effects, thus making it a social obligation for industries to minimize water pollution. During the present study, sample was collected from textile industry of Faisalabad and their analysis showed that the discharge of textile waste water was violating PEPA, (1997) as most of their results was found above their permissible limits of NEQS (1997) including pH, EC,TDS, BOD, COD, SO4 -2 , Cu and Cr. Among the treatment technologies, Phytoremediation is feasible and environmental friendly method for the removal of pollutants from the industrial effluents. A study was carried out to investigate the phytoremediation of pollutants from textile wastewater by Hydrocotyle umbellata L. Reduction in the pollutants load was achieved from 11.37 to 7.03 (pH), 2138 to 1202 (TDS), 18.02 to 15.87 (EC), 900 to 500 (Cl- ), 4833.3 to 2535.1 (SO4 -2 ), 3.26 to 2.01 (NO3 - ), 7000 to 2500 to (CO3 - ), 7500 to 4030 (HCO3 - ), 533 to192 (COD), 246.45 to 86.5 (BOD), 0.138 to 0.13 (Cu), 1.012 to 0.13 (Cr), 0.46 to 0.026 (Zn) by Hydrocotyle umbellata . Phytoremediation using aquatic plants provide a potential opportunity to remove contaminants from the waste water. Aquatic plant Hydrocotyle umbellata accumulated the contaminants when introduced in textile waste water. Hydrocotyle umbellata has the potential to be used in phytoremediation to remove metal pollutants from contaminated textile wastewaters.
