Hydraulics
Influent flow enters the unit through the lower-left connection point, and exits from the
upper right-hand connection point. Solids that are periodically backwashed from the unit
are converted to a continuous flow that exits from the lower-right connection point.
Physical Parameters
The physical parameters menu for the Simple BAF model contains parameters for the
description of the unit, including the characteristics of the media. Figure 7-15 shows the
physical parameters menu. The definitions of the various biofilm parameters (e.g.
maximum biofilm thickness, etc.) are identical to those described in the section on the
Trickling Filter model. The default parameter values for the media characteristics are set
for typical BAF media.
