In communicating with customers, we have found that some customers are very concerned about whether polyacrylamide can decolourise. In the industrial production process,
polyacrylamide is often used as a flocculant for waste water treatment with flocculation and decolourisation.
Anionic polyacrylamide has a remarkable effect in decolourisation. We will introduce the decolourisation principle of polyacrylamide in detail for customers.
1. Adsorption and bridging effect
Anionic polyacrylamide can form hydrogen bonds with suspended particles in water, making it an excellent flocculant. When the anionic polyacrylamide is in full contact with the suspended particles, the polar groups on its molecular chain can adsorb with the suspended particles to form larger flocs. These flocs are easy to settle in the subsequent treatment process, thus achieving decolourisation.
2. Electrical neutralisation
Anionic polyacrylamide can also achieve decolourisation by electrical neutralisation. When anionic polyacrylamide and positively charged suspended particles in contact, the anionic groups on the molecular chain can be suspended particles and the occurrence of electrical neutralization, so that the surface charge of the suspended particles to reduce the stability of water, resulting in the formation of larger flocs, to achieve decolorization.
Polyacrylamide is an indispensable agent for wastewater treatment, and there is no problem in treating wastewater. Of course, some waste water has a high colour and it may be difficult to remove the colour by using polyacrylamide alone. At present, we can choose to use polymerized aluminum chloride, activated carbon and other professional decolorizers for decolorization. We can not only provide customers with high quality polyacrylamide products, but also provide customers with on-site technical support. If you have any waste water treatment problems, please feel free to contact us.
