Disposal of industrial effluents (especially the textile industry) into the drains without prior treatment is a common practice that affects aquatic life and pollutes the soil and groundwater quality. Textile effluents contain organic and inorganic pollutants in terms of high pH, suspended and dissolved solids, chemical oxygen demand, heavy metals, and many other contaminants. Therefore, it is obligatory to dispose off wastewater according to environmental standards. The present study is planned to determine textile wastewater characteristics and recommend efficient and economical treatment options. Wastewater samples from three different industries were collected and analyzed. Nine different treatments using different dosages of alum, activated carbon, and their mixture were used to investigate treatment performance. Analysis of variance and correlation was used to optimize the results. A highly significant correlation was found among the treatments ranging from 92 to 100% for observed parameters. pH, chemical oxygen demand, and total suspended solids were removed significantly. A combination of alum and activated carbon found to be the most efficient treatment. Based on the highly significant results among different parameters, a combined wastewater treatment plant is recommended for a cluster of industrial units.
