ADVANCED WASTEWATER TREATMENT
15-1. Sequence of processes.
A number of different unit operations are used in varius configurations to make up an advanced wastewater
treatment system. The particular situation determines the most applicable process design. The general
sequence of unit operations typically used in advanced treatment is presented in schematic form in figure 15-
1. Table 15-1 presents the applications, advantages, and disadvantages of various advanced wastewater
treatment processes arranged in such a way as to provide a ready comparison between alternative treatment
processes. The applications listed are those for which the process is normally selected. However, many
processes, although selected on the basis of their effectiveness in removal of a particular pollutant, obtain
additional benefits in the control of other waste characteristics.
