Comprehensive Study on Removal Efficiency of Strychonomous Potatorum and Alum as Blended Coagulant for Treatment of Textile Effluent | Chapter 6 | Emerging Trends in Engineering Research and Technology Vol. 4

An explorative investigation was conducted for the viable utilization of Strychonomous potatorum seed powder and alum as a blended coagulant for the treatment of textile mill effluent. In this article, natural coagulant Strychonomous potatorum (SP) and conventional Coagulant Alum Al2(SO4)3 of 10, 20, 40, 60 and 80 mg/L dosages were used. Different proportions of SP: Al2(SO4)3 like 0:0 (P0), 10:90 (P1), 20:80 (P2), 30:70 (P3), 40:60 (P4), 50:50 (P5),60:40 (P6),70:30 (P7), 80:20 (P8) and 90:10 (P9) were used in Pre and post treated textile mill effluents. Formation of floc during coagulation process has been studied in the laboratory extent to ascertain the optimum dosage of blended coagulants and to estimate the percentage removal efficiency of major pollutants in textile mill effluent such as turbidity, TSS, TDS, COD and BOD. when compared with other dosage, from the observed results, the blended coagulant SP: Al2(SO4)3 of 40:60 dosage ratio offers better removal efficiencies with respect to turbidity, TSS, TDS, COD and BOD and it has been suggested as an appropriate dosage for the treatment of textile mill effluent.

Feasibility Studies on Removal Efficacy of Treatment of Textile Effluent Using Natural Coagulants in Erode District | Chapter 12 | Current Research and Development in Chemistry Vol. 2

An explorative investigation was conducted for the feasible use of natural coagulants in the treatment of 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.
