Beer is the world's general drink, is a kind of carbon dioxide, blistering low alcohol brewing wine, is one of the world's oldest alcoholic beverages, it is high-quality barley malt as the main raw material, hops for the spices, Saccharification, fermentation and other processes made. It is the third drink in the world after consumption of water and tea. Its unique wine and refreshing bitter taste, swept the world, it is the world's largest production and sales of wine. So what is the relationship between cationic polyacrylamide and beer? And listen to the novel Xiaobian slowly Road to.
Beer production is the main raw material used is our well-known barley, domestic and foreign common beer brand is also varied, China's beer industry development status is gratifying, but also indicates that China's beer industry production brought about by the beer wastewater The amount is also very large. Beer manufacturing industry is a considerable amount of water consumption of a industry, the difference between the larger enterprises, the average production of 1 ton of beer per ton of water consumption in the 10 tons -15 tons or so, the following we produce a ton of beer, resulting in 20 tons Of the waste water to calculate, China's beer industry emissions will reach 400 million tons per year, however, most of China's brewery comprehensive utilization and waste water treatment is not ideal, to the ecological environment caused serious pollution.
According to the survey, it is found that the waste water discharged from the brewery is often the main project of COD, BOD and SS. We can divide the beer wastewater into two main categories from the main sources of beer production wastewater: 1. Cooling water ; 2. Washing water. It can be seen that the waste water is large, non-toxic and harmful, with a large amount of organic matter, is a high concentration of organic wastewater, in the treatment of such waste water, we recommend the use of cationic polyacrylamide CPAM. Cationic polyacrylamide is one of the polyacrylamide wastewater treatment agents, which has a very significant flocculation and sedimentation effect in organic wastewater treatment for beer and other beverages and food production.
