Rapid mixers, also known as flash mixers, are devices designed to rapidly and uniformly disperse chemicals, such as coagulants, into water. The primary goal of rapid mixing is to facilitate the initial contact between the chemicals and the water, ensuring thorough and even distribution. This promotes the aggregation of suspended particles and colloids, making them more amenable to subsequent treatment processes. Rapid mixers typically utilize high-speed impellers or propellers to achieve rapid and turbulent mixing within a short period. After rapid mixing, the water proceeds to the flocculation stage.
