“…For synthetic turbid water at 100 NTU and 150 NTU, Scylla olivacea shell powder at 2 g/l with optimum alum dosage of 200 mg/l yielded removal efficiencies of about 97% and 98%, respectively. Although the removal efficiencies obtained from Yongyod's work [7] were higher as compared to this work, the optimum dosages of alum used in this work were much lower.…”

“…Also, from the previous research, Yongyod, R. [7] studied water turbidity removal by using Scylla olivacea shell powder as a coagulant aid with alum as a coagulant. The results showed that Scylla olivacea shell powder at 4 g/l with optimum alum dosage of 200 mg/l at 50 NTU synthetic turbid water yielded the removal efficiency up to 97.14%.…”

The main objective of this research is to synthesize silk sericin and silk sericin powder for turbidity removal of synthetic turbid water. Silk sericin used as coagulant aid in this study was extracted from silk cocoons by boiling them with 0.5% (w/w) Na2CO3solution at 90°C for 60 min. Synthetic turbid water with the initial turbidity of about 50 NTU, 75 NTU, and 100 NTU, the turbidity removal efficiencies 89.2±5.41%, 90±3.48% and 87±4.31% respectively. For the powder silk sericin, the turbidity removal efficiencies 96±0.77%, 88±2%, and 96±1.73% respectively. Introduction
