Application of Natural Coagulants in Waste Water Treatment

Abstract : Coagulation is well known technique in water treatment process. Usually this process was done by adding chemicals; treatment methods are difficult and expensive. So there is an increase in demand for the innovative, low maintenance and energy efficient technology for water treatment. Natural coagulants show better results and are concerned by many researchers because of their abundant source, low price, multifunction and biodegradation. The advantage of the plant based coagulants is easily available as they are apparent, economically feasible, easily available and easy to store. The main objective of the present investigation is use of natural coagulants such as Neem seeds powder and Cactus leaves powder etc. After treatment the water samples were analyzed for different parameters like Turbidity, and hardness. Results indicated that cactus showed better influence in removal of physicochemical parameters such as turbidity, hardness etc. from waste water. Application of these low cost plants -based coagulants are recommended for eco-friendly, on toxic and for efficiency.
