Abstract

The use of natural coagulant in waste water treatment has many advantages as compare to the chemical coagulant. It reduces the chemical composition in the waste water after treatment. In addition, it is biodegradable, low toxicity, low sludge production, inexpensive and eco-friendly as compared to chemical coagulant. Annona diversifolia (AD) is used as a natural coagulant in this study. The properties from seed of AD are hypothesized to act as coagulant and reduce the turbidity in water. Thus, effectiveness of the coagulant activity of AD as natural coagulant was investigated and a comparison study with FeCl3 is conducted via coagulation and flocculation using synthetic water (kaolin) It is aimed that AD is able to reduce the turbidity. The purpose of using the seed of Annona Diversifolia is to reduce the chemical substance in the water after treated. Response surface methodology was carried out in this study to find the optimal pH and dosage to treat the synthetic waste water. The optimum treatment conditions for the biopolymer dosage were reported at pH 3 and dosage at 15 mg/L. In contrast, by using ferric chloride the optimum treatment condition is at pH 4 and dosage of 12 mg/L.
