#### Improve Clarifier and Thickener Design and Operation

The idea is to ach ieve a critically loaded settling unit. This is done by constructing operating lines as illustrated in the thickener design example. Figure 9 and Table 2 illustrate the effects of underloading, critically loading, and overloading a thickener. Underloading is the most common condition found in a thickener (see Figure 9).
