Usually, said solution concentration is 0.1%, the non-anionic polyacrylamide solution is not more than a week; cationic polyacrylamide solution was not more than one day, and the solution stability is also related to the concentration of the solution, the concentration distribution is more concentrated (such as 3% to 5%) solution of the storage time is longer, but the 3% to 5% of the solution does not go directly to the sewage treatment, also diluted before use, the cationic polyacrylamide solution pH values ??less than 5.5, more stable, more than 6.0 when rapid failure due to hydrolysis.
