摘要: The pigments (melanoidins) in molasses wastewater are refractory to conventional biological treatment. Ferric chloride was used as coagulant remove color and chemical oxygen demand (COD) from effluent. Using jar test procedure, main operating conditions such pH dosage were investigated. Under the optimum conditions, up 86% 96% of COD removal efficiencies achieved. Residual turbidity supernatant less than 5 NTU Fe3+ concentration negligible because effective destabilization subsequent sedimentation. results high performance size exclusion chromatography (HPSEC) show that low molecular weight (MW) fraction melanoidins is more reactive MW increase lowest organic group related capacity charge neutralization. Aggregate measurement reveals effect on settleability flocs formed, with larger settling rapidly. Charge neutralization co-precipitation proposed predominant coagulation mechanism under conditions.
