Application of polyacrylamide in various water treatment

Polyacrylamide As there are many kinds of sewage, such as municipal Water Treatment, industrial wastewater, etc., the application of polyacrylamide in the treatment process of each enterprise is also very different.

1. Polyacrylamide is used in textile printing and dyeing industry water treatment as sizing agent and finishing agent for fabric post-treatment, which can generate soft, anti-wrinkle and anti-mildew protective layer. Using its strong hygroscopicity, it can reduce the rate of yarn breakage; it can also prevent the static electricity and flame retardant properties of fabrics.

2. When used as printing and dyeing auxiliaries, it can improve the adhesion fastness and brightness of products; it can also be used as a non-silicone polymer stabilizer for bleaching; in addition, it can also be used for the efficient purification of textile printing and dyeing wastewater.

3. The sewage used in chemical plant wastewater treatment has high chromaticity and high pollutant content, mainly due to incomplete reaction of raw materials or a large amount of solvent medium used in production entering the sewage system. There are many biodegradable substances, poor biodegradability, toxic and harmful substances, and complex water quality.

Of course, the application of polyacrylamide in water treatment in various industries is much more than that, it can also treat steel plant wastewater, alcohol plant wastewater, brewery wastewater, food wastewater, coal industry wastewater, pharmaceutical wastewater, etc.
