Chitosan Refinery WasteWater treatment

Yudacentury research shows the treatment effect of chitosan and alkali-aluminum (PAC) compound flocculants on refinery wastewater treatment, and the effects of pH value, stirring time, and sedimentation time on the treatment effect of oil refining wastewater are investigated, and they are compared with polyacrylamide (GD-112 )/PAC compound flocculant on the treatment of oil refining wastewater was compared. The results showed that the CHITOSAN/PAC compound flocculant had the best treatment effect when the compound ratio was 1:5, pH was 7, stirring for 10min and settling for 10min. It has the characteristics of wide adaptability, less dosage, less scum and low toxicity.
