	Hosts	Thickening Procedure

A Thickener is used to represent an equipment resource typically used to host a clarification procedure with a main objective the removal of solids from a sludge and thickening. It similar to the clarifier tank but has a larger size. The procedure can be executed in a batch or continuous mode.

See Clarifier Tank: Equipment Tab

Sizing: Design Mode

In Calculate (Design Mode), the user specifies the Maximum Surface Area and the system computes the Number of Units and the Surface Area. In Design Mode, the Tank Depth is either specified or calculated based on the detention time. For more information on sizing of a thickener tank, see Thickening: Modeling Calculations.

Sizing: Rating Mode

In User-Defined (Rating Mode), the user specifies the Number of Units and the Surface Area. In Rating Mode, the tank depth is always specified.

Costing

The equipment purchase cost is based on the total surface area, and is calculated by the built in model for a clarifier tank with a minimum surface area of 10 m².
