Polyacrylamide dissolution steps as follows:
1. Pour 200g tap water into the beaker.
2. Weigh 0.1g polyacrylamide dry powder.
3. Pour polyacrylamide into the stirred water.
There are obvious particles when polyacrylamide is not dissolved.
PAM can be completely dissolved in water in about 40 minutes.
We have posted an experimental video for you to check:
Anionic polyacrylamide is used for early sewage treatment, and cationic polyacrylamide is used for sludge treatment in the later stage, mostly for biological wastewater.
The next article will explain to you how to choose a polyacrylamide model.
