Biodegradable materials have attracted the industry with the increasingly global trend of biopolymers of low toxicity and durability. Chitosan is a high molecular weight and charging density naturally organic polyelectrolyte (biopolymer), which is obtained from chitin's de-acetylation from the crustaceans shell. Chitosan allows improve its inhibition output through comprehensive processing and composite formation. Chitosan and magnetic particles are cross-links together via co-precipitation method to satisfy the needs of high adsorption, regeneration, fast separation, and cost-effective treatment of wastewater. This would best POME pre-treatment cost-effectively and sustainably. This study was laboratory-based using an actual POME. Optimal dosing of 4 g / L chitosan-magnetic composite particles has reduced turbidity, TSS, ammoniacal nitrogen and COD by 94.6%, 89.2%, 63.8%, and 90.6% respectively. The pH of POME has also changed to 8.35 which followed the discharge standard. In contrast, chitosan seems to need, a much higher dose of 5.5g / L to reach maximum reduction of turbidity, TSS, ammoniacal nitrogen, and COD about 88.7%, 84.7%, 52.2%, and 78.5%, with 8.92 pH value respectively. The synergistic effect of the chitosan-amino-group cationic character in the POME pre-treatment cycle results in increased agglomeration, adsorption, coagulation, and flocculation efficiency. Thus, the potential of fenneropenaeus indicus sp is relevant in POME pre-treatment.
