1. Improve solid-liquid separation efficiency
Brewery wastewater contains a large number of suspended solids, such as yeast, malt residues and proteins, etc. PAM flocculant can make the suspended particles gather each other to form larger flocs through charge neutralization and bridging, which can significantly improve the solid-liquid separation efficiency and promote the settling and filtration of suspended matters.
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. Reduce chemical oxygen demand (COD) and biochemical oxygen demand (BOD)
Brewery 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 a lower water content, which facilitates mechanical dewatering, reduces the volume of sludge, and lowers the cost of sludge treatment and disposal.
5. Promote yeast and protein removal
Brewery wastewater often contains a large amount of yeast and protein, PAM flocculant can effectively promote the aggregation and separation of these components. Yeast and proteins are easy to settle after combining with flocs, which facilitates their removal by means of precipitation or filtration, etc. It reduces the content of yeast and proteins in wastewater and prevents them from influencing the subsequent treatment units.
6. Reducing the amount of pharmaceuticals used
PAM flocculant has efficient 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.
