Granular Media Filtration: Oper. Conds Tab

Variable Definitions, Ranges and Default Values

The following table shows a brief description of the variables appearing in this tab. The table also displays their default values and their generally acceptable range:

Variable	Default Value	Range

○ Removed ? Check the box next to a component to indicate that the corresponding component is removed.	<No>	Yes/No
◙ Binding (%) The binding percentage of a component to the bed.	0.0	0 – 100
◙ Overall Removal Efficiency (%) The total mass percentage of the feed stream that is bound to the bed.	90.0	0 – 100
● Number of Units in Simultaneous Operation The number of parallel units that are required for the operation according to the total demand in bed volume and the equipment’s design constraints.	1	Positive Integer
● Feed Linear Velocity (m/min) The average axial velocity of the feed in the bed.	0.250	Positive

Symbol Key: ○ User-specified value (always input); ● Calculated value (always output); ◙ Sometimes input, sometimes output

Specification Choices / Comments

The following list describes the available specification choices in this tab; for more details on how these are implemented, see Granular Media Filtration: Modeling Calculations.

•Component Removal/Binding Options...

If the Component Binding % is calculated, the user identifies the components that are removed and specifies the Overall Removal Efficiency. Then, the model makes the simplifying assumption that the Removal/Binding percentage of all removable particulate components is the same (equal to the Overall Removal Efficiency). If the Component Binding % is set, then, different removal/binding percentages can be specified for the various particulate components.
