Definition

filtration process in which a fluid is passed through a depth filter

Examples

• A depth filtration process is used to clarify harvested cell culture by removing cells and large debris; A depth filtration process removes insoluble material after cell lysis before purification; A depth filtration process serves as the primary clarification step prior to sterile filtration;

Primitive Class

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

Primitive Rationale

Insufficient constructs are present to create a set of necessary and sufficient conditions

Formal Axioms

First-Order Logic Axioms

DepthFiltrationProcess(x) → FiltrationProcess(x) ∧ ∃y (DepthFilter(y) ∧ hasParticipantAtSomeTime(x, y))

Semi-Formal Natural Language Axioms

if x is a ‘depth filtration process’ then x is a ‘filtration process’ that ‘has participant at some time’ some ‘depth filter’
