Internal and external mixing systems are normally classified as what?

Internal and external mixing systems are primarily classified as hydraulic and/or mechanical due to the methods they employ to achieve mixing. Hydraulic mixing systems utilize the flow of fluids to create turbulence and promote mixing, which is effective in various wastewater treatment processes. These systems can rely on pumps and gravity to distribute the liquid and create the necessary conditions for mixing.

Mechanical mixing systems, on the other hand, involve the use of physical devices like agitators, stirrers, or propellers that mechanically induce mixing through movement. Mechanical means are often used when more intense mixing is required, such as in tanks where solids or viscous materials need to be homogenized.

This classification reflects how mixing is achieved in both systems, emphasizing the importance of the mechanisms involved in promoting effective mixing in wastewater treatment applications.
