Evaluating Coagulation Efficiency of Natural Coagulant for Dairy Wastewater Treatment

Himanshu Patel ^[2] | Anjali Khambete

Abstract: Water is undoubtedly the most important resource from the all natural resources. One of the major source, which pollute the environment is a waste water produced from the dairy industry. Dairy industry is one of the biggest users of water during various processing stages. Wastewater Produce from this processes contain high turbidity, total solids, COD, total dissolve solid. There are variety of coagulation methods for wastewater, which are very costly and those methods are not effective for common people. In this study the attempt is made to find the efficiency of natural coagulant and compare it with chemical coagulant for removal of turbidity. Moringa oleifera is used as natural coagulant and Alum is used as chemical coagulant. The removal of COD, Turbidity, total solids are respectively 56.25 %, 98.70 %, 12.83 % at pH 9 at a coagulant dose of 6.5 gm/L for Moringa oleifera and 62.5 %, 99.75 %, 12.6 % at pH 10 at constant dose of 3.5 gm/L for alum.
