Description
This article describes a continuous thickener model based on ideal Kynch sedimentation theory, as presented by King (2002, 2012).[1][2].
The model predicts the achievable underflow concentration and flowrate, based on the thickener size and the settling characteristics of the slurry.

Excel
The King thickener model may be invoked from the Excel formula bar with the following function calls:
=mdUnit_Thickener_IdealKynch(Parameters as Range, Size As Range, Feed as Range, Density as Range, SettlingVelocity as Range, Optional NumChartPoints as Integer)
Invoking the function with no arguments will print Help text associated with the model, including a link to this page.

The required inputs are defined below in matrix notation with elements corresponding to cells in Excel row ([math]\displaystyle{ i }[/math]) x column ([math]\displaystyle{ j }[/math]) format:

where:

- [math]\displaystyle{ \text{Underflow mode} }[/math] specifies the targeted underflow condition, 0 = Target underflow concentration, 1 = Target underflow flow rate, 2 = Limiting capacity
- [math]\displaystyle{ \mathit{CD}_{\rm Target} }[/math] is the underflow concentration operating target for the thickener (v/v)
- [math]\displaystyle{ \mathit{QD}_{\rm Target} }[/math] is the underflow flow rate operating target for the thickener (m{sup}3{/sup}/h)

However, particle size-level information is included to maintain consistency with the data structures used by other unit models in flowsheet simulations.
