Sizing: Design Mode

In Calculate (Design Mode), the user specifies the Maximum Horizontal Area and the system computes the Number of Units and the Number of Plates per Units. For more information on sizing of an IP clarifier tank, see IP Clarification: Modeling Calculations.

Sizing: Rating Mode

In User-Defined (Rating Mode), the user specifies the Number of Units and the Number of Plates per Units.

Costing

The equipment purchase cost is based on the total horizontal area, and is calculated by the built in model for a IP clarifier tank with a minimum area of 5 m2. Other parameters that affect the costing is the installation location (underground or above ground) and the material.
