Hello everyone, I am your water treatment assistant. Today we are going to talk about the reasons for the poor precipitation effect of polyacrylamide in water treatment. Have you also encountered such a problem? Now let’s take a look at what may be the reasons.
- Improper selection
PAM comes in non-ionic (NPAM), cationic (CPAM), and anionic (APAM) types. Picking the wrong one weakens results.
- Improper dosage
Using too much or too little can reduce its effectiveness. More isn’t always better!
- Water quality impact factors
pH levels, temperature, or types of particles in water can interfere with PAM’s performance.
- Insufficient mixing
If the polyacrylamide and the suspended substances in the water are not fully in contact, it may not have a good precipitation effect.
- Initial dosing
The first use of polyacrylamide may require some time to adjust and find the most suitable dosing amount and method.
- PAM Quality
Did you know? If PAM is stored for too long or under unsuitable conditions, its performance may be degraded.
- The degree of turbulence in the system
If the system is too turbulent, it may destroy the flocs formed by polyacrylamide, resulting in poor precipitation effect.
- Interfering Substances
Heavy metals, organic matter, or other chemicals in water can block PAM’s action.
- Other chemicals in the water treatment process
Other chemicals are also used in the water treatment process, such as PH regulators, scale inhibitors, etc., which may interact with polyacrylamide.
- Water treatment process design
Badly designed reaction tanks, mixing times, or clumping conditions hurt results.
