Comprehensive Study on Removal Efficiency of Strychonomous Potatorum and Alum as Blended Coagulant for Treatment of Textile Effluent

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.
