Definition

role held by a material entity when it is added to the material being filtered or deposited onto a filter to improve filtration performance

Explanatory Notes

Here, improving filtration performance may include increasing flow, reducing filter clogging or blinding, increasing cake permeability, improving particle retention, or extending filtration capacity.

Examples

• the filtration aid role of diatomaceous earth added to a cell-culture harvest before depth filtration; the filtration aid role of diatomaceous earth deposited onto a filter as a precoat; the filtration aid role of perlite added to material being filtered during clarification

Primitive Class

This class is declared primitive and it does not have necessary and sufficient condiftions defined.

Primitive Rationale

There are insufficient constructs to create a set of necessary and sufficient conditions

Formal Axioms

First-Order Logic Axioms

FiltrationAidRole(x) → Role(x) ∧ ∃m (MaterialEntity(m) ∧ roleOf(x, m))

Semi-Formal Natural Language Axioms

if x is a ‘filtration aid role’ then x is a ‘role’ that is the ‘role of’ some ‘material entity’
