Chitosan from Mytilus virdis linneaus Shell as A Natural Coagulant

Abstract

Green mussels (Mytilus virdis linnaeus) shell is one of the marine resources that can be used as raw material chitosan. Coagulant can remove turbidity through coagulation and flocculation process using coagulant. Biopolymers from natural coagulant safer and environmentally friendly so can subtitute synthetic coagulant. The use of chitosan as a coagulant in this study used synthetic turbid water using distilled water, suspended solids representing kaolin and humic acids which represents organic matter. Chitosan was used with variations in pH and coagulant dosage. Chitosan remove turbidity optimum at pH 7 at a dose of 300 mg/L of 95.15%.
