Abstract: The present study was undertaken to evaluate the efficiency of an effluent treatment plant (ETP) of a polyester textile dyeing industry with 150-250 m³/day average inflow in Haridwar, Uttarakhand, India. The raw effluent was analysed for 18 physico-chemical parameters and eight heavy metals for a period of one year. The study revealed that raw wastewater has high chemical oxygen demand (COD) (2,461.0 ± 48.45 mg/L), colour (892 Pt-Co), sulphate (6,620.0 ± 7.22 mg/L) and electrical conductivity (EC) (2,906.0 ± 5.77 μS/cm) respectively. The treated effluent from ETP showed a significant reduction in colour (71.28%), EC (75.71%), alkalinity (76.04%), biological oxygen demand (BOD) (53.34%) and chemical oxygen demand (COD) (53.53%). However, colour, BOD and COD exceed the standards by Central Pollution Control Board (CPCB), India for safe discharge of industrial effluent in inland surface water and based on the results it is recommended that pollutant level in polyester textile dyeing effluent is of major concern requiring regular monitoring and further advanced treatment.
