In the beer industry, wastewater treatment is a complex and arduous task. A large amount of wastewater is generated during the beer production process, which contains high concentrations of organic matter and nutrients. It must undergo pretreatment before it can be effectively purified in traditional wastewater treatment plants. Polyacrylamide (PAM), a high-molecular-weight polymer, has become an efficient solution for wastewater treatment in breweries. This article will explore how PAM can improve the wastewater treatment process in breweries and contribute to sustainable development.
The characteristics of brewery wastewater
Beer production involves multiple stages, including malt making, grinding, mashing, boiling, filtration, hop addition, fermentation, maturation, clarification and packaging. Wastewater from different sources will be produced in these processes, mainly including:
- Washing water in the malt production process
- Solidified cleaning water
- Washing water for the saccharification process
- Fermentation tank cleaning water
- Canned and bottle washing water
- Cooling water
- Washing water in the finished product workshop
- And some domestic sewage
These wastewater often contain organic substances such as proteins, yeast, polysaccharides and residual grains. The water quality is complex and the treatment is difficult.
How does PAM Improve the Wastewater Treatment in Breweries
How to Choose Polyacrylamide for Brewery Wastewater Treatment
In the wastewater treatment of breweries, choosing the appropriate type and dosage of PAM is very crucial. To achieve the best treatment effect, it is necessary to determine the molecular weight, ion type and dosage of PAM through laboratory and on-site tests in combination with the specific components and water quality characteristics of the wastewater.
The key factors include:
The types of suspended solids in wastewater: Beer wastewater usually contains organic substances such as proteins, yeast, and polysaccharides, especially yeast and malt proteins.
The pH value of wastewater: Different pH values of wastewater can also affect the performance of PAM.
The turbidity of wastewater: Wastewater with high turbidity requires more efficient flocculants to ensure sedimentation efficiency.
PAM is mainly classified into three types: cationic, anionic and nonionic. For beer wastewater with high organic matter content and negative charge, high-molecular-weight cationic PAM is usually the best choice. Its strong flocculation ability can quickly settle impurities and improve the efficiency of solid removal.
The dosage of PAM is crucial to the effectiveness of wastewater treatment. Adding too much PAM may lead to waste and excessive sludge production, while adding too little may result in poor treatment effect. Therefore, accurately controlling the dosage of PAM is of vital importance.
