摘要：In this present study the effectiveness of Acanthocerous tetragonus (AT) as a coagulant to remove the colour of synthetic textile waste water contains Congo Red (CR) and Direct Blue (DB) dye was analyzed. Experiments were carried out for initial dye concentration of 100-500 ppm and coagulant dose varies between 1-6ml of AT and 1-6gm of Alum .It was observed that the maximum colour removal was attained at 400ppm initial dye concentration and 4ml coagulant dose for AT and 6 gm of alum dose. On comparing with the commercial coagulants like alum this novel natural coagulant AT produced less quantity of sludge. The sludge volume index (SVI) of AT and Alum was 30 and 45 mL/gm in Direct blue dye solution and 35 and 48 mL/gm for Congo red dye solution respectively. Based on the experimental results, it was decided that the natural coagulants like AT will be a very effective one, compared to metallic salts like alum.
