Abstract - The study investigates the safe drinking water remains a critical issue, particularly in developing nations where waterborne illnesses claim numerous lives annually. The study evaluates the effectiveness of natural coagulants— Tamarindus indica, Strychnos potatorum, and Moringa oleifera in removing Turbidity and Total dissolved solids (TDS) from water. Experimental results demonstrate that Moringa oleifera achieves the highest Turbidity removal rate of 97.97% at 30 mg/l dosage, pH 5, and 30 minutes. Tamarindus indica and Strychnos potatorum achieve 92% and 86% Turbidity removal, respectively. Regarding TDS, Moringa oleifera also shows superior performance with a 95% removal rate, followed by Tamarindus indica (93%) and Strychnos potatorum (91%). The findings indicate that Moringa oleifera is the most effective natural coagulant for improving water quality, making it a promising option for water treatment in resource-limited settings.
characteristics. The significant seasonal variation in turbidity is one of the issues with treating surface water. Many treatment facilities in impoverished nations currently operate under arbitrary restrictions, especially when it comes to chemical doses. In addition, insufficiently trained laborers and a lack of lab space to track the process performances needed to run the plants. In the water treatment business, coagulation-flocculation, followed by sedimentation, filtration, and disinfection often with chlorine is employed globally before the distribution of treated water to consumers(1).To assess and contrast the efficiency of Tamarindus indica, strychnic potatorum, and drumstick seeds as natural coagulants for the extraction of turbidity and total dissolved solids (TDS) from water samples. To ascertain the ideal dosage of each coagulant required to minimize turbidity and obtain the highest possible TDS.To determine the capacity of the seed extracts without the assistance of coagulants and to lessen the turbidity of the artificial turbid water.To offer a technologically sound and environmentally sustainable means of enhancing people's quality of life.researching the biosorbent's chemical and physical characteristics.To assess the natural biosorbents' ability to disinfect.

1.INTRODUCTION One basic need that all organisms, including humans, must have is water. Utilizing limited resources can help living things on this earth. Approximately 75% of the current global population resides in developing nations. Approximately There are 1.2 billion individuals lack access to safe drinking water, and every year, over 6 million children in underdeveloped nations perish from bloody diarrhea. Nonetheless, it is inconceivable and intolerable in any circumstance that waterborne illnesses continue to claim the lives of 25,000 people on average each day in underdeveloped nations. At the same time, millions more endure the crippling consequences of these illnesses (1). For a community to be healthy and safe to drink, all water sources must be purified before being used. Water is made appealing to consumers and safe by a variety of techniques. The technique used is established by the raw water's
