A Study On Strychonomous Potatorum As Natural Coagulant For Treatment Of Textile Waste Water

Abstract

A preliminary investigation was carried out for the feasible use of Strychonomous potatorum as a natural
coagulant to the treatment of textile waste water. In this paper, natural coagulant Strychonomous potatorum and Chemical
Coagulant Alum of 10, 20, 40, 60 and 80 mg/L dosages were used. Floc formation in coagulation process had b een studied in
the laboratory scale to determine the optimum dosage of natural and chemical coagulants. Various 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 wastewaters with coagulants were considered to evaluate the percentage
removal efficiency on the major pollutants of concern in textile effluent such as turbidity, TSS, TDS, COD and BOD. From
the observed results, the blended coagulant SP: (Al2(SO4)3 of 40:60 dosage ratio gives better removal efficiencies with
respect to turbidity, TSS, TDS, COD and BOD and appears to be suitable for textile waste water treatment, when compared
with other dosage ratio
