| Abstract | This study investigated the viability of using MIEX? GOLD (MIEX?) and AMBERLITETM FPA98 Cl (AR) ion-exchange resins to remove dissolved organic carbon (DOC) from sugar mill effluent (SME) in laboratory-scale experiments; effects of resin dose contact time and pH on DOC removal were also investigated. Sorption kinetics of both resins were fitted to pseudo-second orders and then to pseudo-first orders, while equilibrium sorption was fitted to the Freundlich isotherm. The initial rate constant and sorption capacity were higher for MIEX? (0.31 mLmg-1min-1 and 0.33 mg/mL) than for AR (0.09 mLmg-1min-1 and 0.23 mg/mL).The 5 mL/L dose of MIEX? with a contact time of 20 min removed 54.82 % of the DOC; the 5 mL/L dose of AR removed the same amount of DOC with a contact time of 60 min. Through non-targeted analysis, both resins selectively removed carbohydrate-like, lignin-like, and condensed aromatic structure DOM with more oxidized characters. A pretreatment with MIEX? or AR, followed by FeCl3 coagulation/sedimentation, not only reduced 87.5 % of the coagulant demand but also removed higher amounts of DOC and UV254 compared to FeCl3 coagulation/sedimentation alone. Both resins have potentials as a pretreatment for enhanced coagulation processes to reclaim SME. |
