textile effluent in Erode district of Tamil Nadu (India). In this article, three natural coagulants namely Moringa oleifera, Tamarina indica, Strychonomous potatorum of 10, 20, 40, 60 and 80 mL dosages were used to spot the suitable one as primary coagulant. Floc formation in coagulation process had been studied in the laboratory scale to determine the optimum dosage of natural coagulants. Pre and post treated textile wastewaters with natural coagulants were considered to evaluate the percentage removal efficiency on the major pollutants of concern in textile effluent such as pH, turbidity, TSS, TDS, COD and BOD. Influence of settling time of natural coagulants on the removal of physiochemical characteristics of textile effluent was studied. From the observed results, the natural coagulant Moringa oleifera gives better removal efficiencies with respect to turbidity, TSS, TDS, COD and BOD and appears to be suitable for textile effluent treatment in Erode district, when compared with Tamarina indica and Strychonomous potatorum. The surface morphology of the untreated textile effluent and treated textile effluent with optimum dosage of M. oleifera, T. indica and S. potatorum were observed by means of SEM analysis.
