Abstract: The present study is related to determination of optimum dosage of natural coagulant and chemical coagulant to bring down the turbidity of the considered river water by maintaining different pH ranges. The conversion of waste water into unpolluted water as became challenge now a days. In the present investigation, a focus is made on Turbidity characteristic of waste water and an attempt is made to treat water so as to utilize it by removing its turbidity. After removal of turbidity, the water should undergo again some stages of purification. Before undergoing further purification, water should be made turbid free. To make water a turbid free, two types of coagulants are considered in this present study which are natural coagulant and chemical coagulant. The coagulant is orange peel powder natural one and the other is Alum, a chemical coagulant. Three series of water samples were considered by varying pH values (6, 7 and 8.5). Other qualities of water like Turbidity, alkalinity and acidity were also tested before and after the process of coagulation. In this study an optimum dosage of coagulant was determined. The samples of river were collected from nearby flowing Kundu River, Nandyal (M), Kurnool (Dist)-A.P. The test results show that the optimum dosage of orange peel powder was found at 103 mg/l with 0.3 NTU Turbidity with Turbidity removal efficiency of 98.68%and by using Alum the optimum dosage was found at 26 mg/l with 0.3 NTU Turbidity with Turbidity removal efficiency of 98.68%
