Magnetic Flocculation for Advanced Treatment of Vitamin E Production Wastewater

Abstract: Effects of the sorts and concentration of flocculants, types of PAM and pH value on the advanced treatment of Vitamin E production wastewater by magnetic flocculation process were studied. When the effective flocculant prepared in our lab was chosen as the flocculating agent and its concentration was 1.0 g/L, The cationic PAM 802 was as the coagulant aid and its concentration was 15 mg/L, pH was controlled as 9.0, CODCrremoval rate achieved the maximum of above 31%.

“…However, the application of this method in FGD wastewater treatment is limited due to the high energy consumption, fast electrode consumption, high operation cost, less wastewater treatment and other problems [20]. Magnetic coagulation has been proved as an effective upgrade technology for traditional coagulation, which has been applied in wastewater treatment [21]. The magnetic seed promotes the formation of flocs, which has the following advantages: 1) high separation rate; 2) high SS remove efficiency and stability, promote the removal efficiency of dissolved matters; 3) more compacted flocs and chemical sludge reduction [22].…”
