| Summary: | 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. |
