摘要：During this work, we treated the effluents from hot-dip galvanizing. For this we usedthe coagulation/flocculation process using aluminum sulphate as coagulant andflocculants which are PVAc and PVAs. From the results obtained, we observed thatthe effluent rate values of treated effluents were recorded at 96.18% for suspendedsolids, 98.35% for turbidity and 98.94% for conductivity (μs/cm), 98.38% of thechemical oxygen demand and 98.50% of the biochemical oxygen demand in the caseof treatment with the aluminum sulphate/PVAs. However, treatment with thealuminum sulphate/PVAc, we obtained 95.83% removal for suspended solids, 98.17%for turbidity, 67.57% for conductivity (μs/cm), 98.48% for the chemical oxygendemand and 98.48% of the biochemical oxygen demand.
