Description

Technical Field

[0001] The utility model relates to the technical field of tap water treatment, in particular to a PAM dispensing system for a water plant. Background Art

[0002] Polyacrylamide (PAM) is a huge linear organic high molecular polymer. In water treatment, it is often used as a coagulant and dehydrating agent to improve the floc structure and make small and loose flocs become coarse and dense. The mechanism of action is the adsorption and bridging of high molecular substances.

[0003] The water plant prepares PAM solution for water treatment. However, PAM itself dissolves slowly and has high viscosity.
