Yes, but polyacrylamide is different from other sewage treatment agents. It has many models and molecular weights, and the effects of different models and molecular weights on different sewage are very different, even the effects are very different. Therefore, before choosing polyacrylamide, it is generally necessary to choose a suitable model.
Both anions and cations are used in sewage treatment. Generally speaking, anionic poly (alkenyl amide) is mostly used for flocculation treatment and cationic poly (alkenyl amide) is mostly used for sludge pressing treatment.
