Natural waterways are contaminated due to industrialization , urbanization , population growth etc .,degrading their quality.contaminated waterways cause numerous health and environmental hazards. Therefore,it is imperative to remove contaminants. Coagulation is one of the efficient primary chemical treatment methods that could be used to treat such contaminants. Natural coagulants have gained popularity in the water and waste water treatment industry due to their advantage over chemical coagulants. Natural coagulants are derived from either plants,animals,or micro organisms. This study has elaborated on the nature and mechanisms, and types of natural coagulants. In this review work,many studies have proposed several types of natural coagulants . however , plant -based on their application and efficiency in water and waste treatment. The present study deals with the evaluation of the treatment efficiency of natural coagulants moringa oleifera , and tamarind seeds . the experiments were conducted at various proportions of dosages of natural coagulant (moringa oleifera ,tamarind seeds). the physio -chemical parameters of waste water are measured before and after the treatment to evaluate the removal of efficiency on the major pollutants of concerned in waste water treatment ,such as PH,Turbidity, Total dissolved and Suspended solids. Then, the experimental studies were carried out to find out the optimum dosage of natural coagulants . In this project optimum dosage of moringa oleifera and tamarind seeds is at 60 mg/l. It was found that natural coagulants was effective in reducing turbidity by 70 to98% in surface lake water samples.the maximum removal efficiency in moringa oleifera is higher than tamarind seeds on the major pollutants of concerned in waste water treatment ,such as PH,Turbidity,Total dissolved and suspended solids.
