1. Improve solid-liquid separation efficiency
Food processing wastewater contains a large number of suspended solids, such as food residues, grease and protein, etc. PAM flocculant, through the charge neutralization and bridging effect, makes the suspended particles aggregated with each other to form larger flocs, which significantly improves the efficiency of solid-liquid separation, and promotes the settling of suspended matter and filtration.
2. Improvement of water quality
After the use of PAM flocculant treatment of wastewater, its suspended solids, turbidity and organic content is greatly reduced, the effluent water quality is significantly improved. This helps to meet the discharge standards or provide better influent conditions for subsequent treatment processes, improving the overall effectiveness and stability of the treatment system.
3. Reduction of Chemical Oxygen Demand (COD) and Biochemical Oxygen Demand (BOD)
Food processing wastewater has a high content of organic matter, through the use of PAM flocculant, most of the organic material and suspended solids can be removed, significantly reducing the COD and BOD value of wastewater, reduce the load of subsequent biochemical treatment units, improve the efficiency of biochemical treatment.
4. Improve sludge dewatering performance
PAM flocculant can make sludge particles form larger flocs, improve the structure of sludge, and improve the performance of sludge dewatering. The sludge treated with flocculant has lower water content, which facilitates mechanical dewatering, reduces the volume of sludge, and lowers the cost of sludge treatment and disposal.
5. Promote the removal of oil and grease
Food processing wastewater often contains a large amount of oil and grease, PAM flocculant can effectively promote the aggregation and separation of oil and grease. The oil and grease combined with floc is easy to float to the surface or settle, which is convenient to remove by flotation or sedimentation, etc., reducing the oil and grease content in wastewater and preventing the impact of oil and grease on the subsequent treatment unit.
6. Reduce the use of pharmaceuticals
PAM flocculant has high efficiency flocculation performance, the use of relatively small amount, you can achieve good treatment results. Compared with other flocculants, the use of PAM can reduce the total amount of chemicals used, reduce treatment costs, and reduce the negative impact of chemicals on the environment.
