Textile industry is one of the major industries in the world that provide employment with no required special skills and play a major role in the economy of many countries. The textile industry utilizes various chemicals and large amount of water during the production process. Colour is the major pollutants present in the effluent from various textile industries. These are highly toxic to living things and have hazardous effect on their health. Thus removal of colour using natural flocculant is a major step towards the protection of natural resources. Coagulation-flocculation is the most widely used method and 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 along with SS, DS, TS and COD from waste water by using natural flocculant i.e. Cactus, Aloevera, and combination of Cactus & Aloevera. The colour removal efficiency of flocculant was investigated by batch wise coagulation flocculation method. The effect of various important parameters on the % removal of colour was studied to find the optimum condition for the maximum removal of colour. The parameters like pH, coagulant dose, flocculant dose, coagulant mixing time, coagulant mixing speed, flocculant mixing time, flocculant mixing speed, setting time & concentration of waste water were investigated. These parameters for Cactus were found to be 12, 10 ml/L, 20 ml/L, 2 min, 140 rpm, 15 min, 70 rpm, 6 min, 300 ml/L respectively, for Aloevera were Journal of Water Resource Engineering & Pollution Studies Volume 5 Issue 1 found to be 11.5, 10 ml/L, 100 ml/L, 2 min, 140 rpm, 15 min, 30 rpm, 1 min, 300 ml/L respectively and simultaneously for combination of Cactus & Aloevera were found to be 12, 10 ml/L, 10% + 80% (Cactus + Aloevera dose) ml/L, 2 min, 140 rpm, 25 min, 50 rpm, 10 min, 300 ml/L respectively. These natural flocculants gives maximum colour removal efficiency in the range 85-100%. The colour removal efficiency was found in between 85-100% for all parameters. All the result was validated on the basis of mathematical analysis. All the graphs were fitted to various trend lines out of which polynomial third order curve is best fit to experimental work as the coefficient of correlation (R2 value) is closer to unity.
