Colour Removal from Textile Effluent by Using Biomaterials - An Experimental Evaluation

摘要

Coagulation flocculation is the most widely used method is applicable for the removal of the colour even at low concentrations. This paper represents the results of investigations carried out for the removal of colour from waste water by using natural flocculent i.e. Cactus, aloe Vera, ferrous sulphate and combination of cactus and aloe vera. The parameters like ph, coagulant dose, flocculent dose, mixing time of coagulant, mixing speed of coagulant, mixing time of flocculent, mixing speed of flocculent, setting time, concentration of waste water were investigated. The bio-flocculants cactus, aloe Vera and combination of both gives maximum colour removal efficiency of 89.33%, 82%, 83% respectively. All the result was validated on the basis of mathematical analysis.
