Water Treatment Chemicals- PAM

Latest company case about Water Treatment Chemicals- PAM

 


PAM-polyacrylamide is a water-soluble high-molecular polymer, insoluble in most organic solvents, and has good flocculation, which can reduce the friction resistance between liquids. According to the ionic characteristics, it can be divided into non-ionic, anionic, cationic and amphoteric Four types of type.

 

It can be seen that polyacrylamide has a strong flocculation effect. No matter what kind of sewage, after adding polyacrylamide, it will quickly separate.

 

The principle is that polyacrylamide has a long molecular chain structure, and the charge on the molecular chain can effectively neutralize the charge on the surface of suspended particles and other particles, and the adsorption effect of positive and negative charges can adsorb pollutant particles in sewage. In its long polymer chain, it achieves the purpose of solid-liquid separation.

 

In addition, the groups contained in polyacrylamide can replace the hydrogen bonding of particles such as pollutant suspended matter with water, thereby separating the particles such as pollutant suspended matter from the water to achieve the effect of purifying water quality.

Simply put, when polyacrylamide is dissolved in water, it will form a colloid, which can adsorb impurities in the sewage on itself and then condense into a mass and deposit it.

 

However, it should be noted that polyacrylamide can not remove all pollutants in sewage, it can only remove impurities and make sewage clear.
