ABSTRACT

Water pollution has become a major concern all over the world due to rapid industrialization. The objectives of this study were to assess the Effective use of Artocarpus Heterophyllus Leaf and Citrus Limon Leaf as natural Coagulants for Purification of Water from Chalakudy River an alternative to the current commercial synthetic coagulant such as aluminium sulphate and to optimize the coagulation process. Various coagulant combinations with which the raw water from 3 sites of Chalakudy river is treated. Based on the experimental results, shows Citrus Limon Leaf powder used as coagulant increased pH and it is negatively affected on turbidity removal. And in natural coagulants Artocarpus Heterophyllus Leaf powder used for coagulation, the optimum dosage of Jackfruit tree leaf powder as coagulant is found to be 10mg/l. The optimum pH of jackfruit leaf powder found to be 7.7.The reduction of turbidity is 51.9%. reduction BOD is 45.8%, reduction in total dissolved solids is found to be 57.5%. Natural coagulant is a naturally occurred plants based coagulant that can be used in coagulation-flocculation process of wastewater treatment for reducing turbidity. It could be concluded that Artocarpus Heterophyllus Leaf powder showed tremendous potential as a natural coagulant for after treatment purposes and could be applied in the pretreatment stage. The results proved that the use of jack fruitleaf powder is natural coagulant is a feasible option in enhancing the efficiency of turbidity removal in water treatment. Furthermore, the usage of this natural coagulant will reduce the production of non-biodegradable chemical sludge to the environment, lower the sludge handling and treatment costs and it works as a low cost natural coagulant agent for coagulation process in water treatment plant and act as a significant environmental friendly product.
