Cationic Polyacrylamide What Is The Connection With The Beer?
Oct 31, 2017

Cationic polyacrylamide is a water-soluble polyelectrolyte, with its molecular chain with amino groups, which can change the cation content by changing the amino content. It is widely used in sewage treatment and sludge regulation. Flocculation mechanism is mainly through the role of electricity and bridge to stabilize the particles, so both the coagulant and flocculant. Cations are generally prepared by chemical modification of polyacrylamide and copolymerization of acrylamide and cationic monomers.

①pam modified

② pam and cationic monomer copolymerization, a variety of monomer copolymerization is the fastest growing method, but also the most used method.

Polyacrylamide is water-soluble, rainfall can be evenly spread with moisture and penetrate into the soil pores were saturated. Since cationic polyacrylamide has flocculation properties, one component can adsorb multiple soil particles when a suspended soil particle is present, and a soil particle can be adsorbed by multiple component molecules, resulting in large flocculation. These fels, reducing the surface of the rains on the surface of the splash, and the role of molecular groups to reduce the particle's starting force.

Brewery sewage treatment and cationic polyacrylamide are inseparable

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?

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 sewage treatment agent, in the beer and other beverages and food production produced by the organic wastewater treatment has a very significant flocculation effect, the current well-known brands such as China's walnut brand In the treatment of waste water is used in the production of cationic polyacrylamide.
