Abstract

A batch system was applied to study the effect of using macroporous cross-linked chitosan–Tripolyphosphate (TPP) beads on Chemical Oxygen Demand (COD) values and turbidity in Sasirangan wastewater. The ionic cross-linking reagent sodium tripolyphosphate was used to obtain more rigid chitosan beads, and sodium bicarbonate was added as a porogen. The COD value was analyzed using the titrimetric method and the turbidity value using the turbidimetric method. This analysis was used to study the effect of dose and pH on the performance of beads in sasirangan wastewater. SEM characterization of the beads showed that NaHCO₃ as porogen enlarged the pores in the beads of chitosan-TPP, and FTIR characterization showed interactions among chitosan, chitosan–TPP beads, and wastewater. The results showed that higher chitosan dosages resulted in increased final COD values in sasirangan wastewater, and the higher the pH, the higher the COD value. The addition of beads reduced the turbidity value of the sasirangan wastewater, where higher doses led to greater turbidity reduction, with the optimum achieved at 400 mL/L. The pH conditions did not affect the reduction in the turbidity value where with less than 1% variation observed.
