Abstract

Natural raw water's quality has decreased as a result of several health and environmental risks brought on by industrialization, urbanization, demographic change, etc. Natural-based coagulants are used frequently to remove pollutants since they are accessible, affordable, eco-friendly, and quickly biodegrade as compared to inorganic-based coagulants. This natural-based coagulant is employed in this study to minimize raw water turbidity and boost drinking water quality. The raw water is taken from the Kalyani dam, Tirupati, Andhra Pradesh, and the coagulants such as Strychnos potatorum (SP), Ocimum sanctum (OS), and Citrus sinensis (CS) are used in this research. These natural coagulants are first cleaned, rinsed with tap water, dried, crushed, and then finely sieved to produce a powder. The turbidity achieved the best removal efficiency for Strychnos potatorum, Ocimum sanctum, and Citrus sinensis is 89%, 78%, and 72%, respectively. Other water quality measures, including alkalinity, hardness, pH, and total dissolved solids, are also evaluated to determine the coagulant's performance in the treatment of drinking water. The outcomes demonstrated that natural coagulants performed consistently well concerning water parameters. Thus, natural coagulants are excellent alternatives to chemical coagulants or coagulant aids, particularly in developing areas.
