When treating sewage and tap water on many occasions, anionic polyacrylamide and cationic polyacrylamide are used together to produce a more significant and synergistic effect than one polyacrylamide alone. The performance of amphoteric polyacrylamide in reducing surface tension is much greater than that of cation or anion alone under the same conditions. To reduce surface tension, it is necessary to use both anionic and cationic polyacrylamides, both of which will produce white precipitates and lose their effectiveness if not used properly. Products with amphoteric characteristics can complete the synergy of anion and cation without any residues. In complex and changing water quality situations, it is more convenient and effective to use amphoteric polyacrylamide as a flocculant.
Due to the increasingly complex nature of urban sewage, the requirements for sludge dewatering agents in sewage treatment are becoming higher. Cationic polyacrylamide is not suitable for some sludge dewatering. Therefore, PAM, an amphoteric sewage dewatering agent, has been developed for this situation. After the dehydration test and use in various sludge, it is better than PAM with a single ionic property. In particular, amphoteric polyacrylamide has a more prominent effect when used to dewater the sludge from oil refineries and chemical plants.
The effect of amphoteric polyacrylamides is incomparable to polyacrylamide with a single ionic property. It can improve the water filtration speed under the screen, and reduce the loss of fiber filler, especially in terms of retention and drainage. It also has a good effect on the wet end system, promoting and compensating for paper smoothness, strength, and two-sided difference.
