Floatation<br />

Figure 8-8 - Operational Parameters for the DAF Unit<br />

The Flotation parameters, shown in Figure 8-9, are used to define the variables<br />

contained within the model (Equation 8.1). The maximum floating velocity provides an<br />

upper boundary limit for the model. The next variable is the expected floating velocity<br />

under the optimal air-to-solids ratio, as defined under the operational input form. The<br />

hindered zone and free floating zone floating parameters control the floating velocity<br />

defined in Equation 8.1. There will likely be a fraction of solids, which cannot be<br />

removed by flotation. This fraction is characterized as the non-floatable fraction and an<br />

upper boundary for this parameter as a concentration is set as the maximum nonfloatable<br />

solids.<br />
