Polyacrylamide is a linear organic high molecular polymer, and also a high molecular water treatment flocculant product. It can specifically absorb suspended particles in water and act as a link and bridging between particles to make fine particles form a comparison. Large flocs, and accelerate the speed of precipitation. This process is called flocculation, because of its good
flocculation effect, PAM is used as a flocculant in water treatment and is widely used in sewage treatment.
