How to choose Polyacrylamide(PAM) according to pH

Polyacrylamide(PAM) requires different types to treat water with different pH. So when we know the pH, how do we choose Polyacrylamide(PAM)? Generally speaking, we all know that the pH of water is 1-14.

Generally, the pH of drinking water in our lives is 7, which is neutral water quality. If the pH is greater than 7, the water quality is alkaline. Less than 7, called acidic water quality. So we use Polyacrylamide(PAM) to treat such water quality, how do we choose the type?

Here, the top manufacturer(Henan SINOWIN Chemcial) tells you that Polyacrylamide(PAM) is divided into anionic Polyacrylamide(PAM), cationic Polyacrylamide(PAM) and non-ionic Polyacrylamide(PAM). When dealing with water quality within the effective pH range, the general situation is as follows:

 1. The pH is 5-14, using anionic Polyacrylamide(PAM);

2. The pH is 1-8, using non-ionic Polyacrylamide(PAM);

3. The pH is between 7-14, and cationic Polyacrylamide(PAM) is used.

When we use Polyacrylamide(PAM), we must realize the neutrality of the water quality in order to achieve good results. Of course, there is also the use of Polyacrylamide(PAM) by adjusting the pH, which is also very good, but this is a small trouble.
