1 Identity-Giving FunctionFunção Identitária
Function class
FiltrationFunction ⊑ DesignedFunction
Realized in
FiltrationProcess ⊑ PlannedProcess
Filtration is the identity-giving function that distinguishes filters from other separation equipment. It specifically involves selective removal of unwanted constituents (typically solids from fluids) based on physical barriers, size exclusion, or other selective mechanisms. This function encompasses both physical filtration (removing particles) and signal filtration (removing unwanted data components).
2 Genus DeterminationDeterminação do Gênero
Separatorbfo:Object (BFO_0000030)
Filter is a specialized type of separator - the CFIHOS and POSC Caesar definitions explicitly state 'A separator intended to remove solids from vapour or liquid'. The already-enriched separator class (SeparationFunction, genus: Vessel) exists in the ontology. However, filters are more generally Assembly-level equipment that can be standalone units with multiple components (filter housing, filter element, cleaning mechanisms, etc.), not necessarily vessel-based like bulk separators.
3 Differentia SpecificaDiferença Específica
∃bearerOf.FiltrationFunction ⊓ ∃participatesIn.FiltrationProcess

A filter is distinguished from other separators by its function of selective removal of specific unwanted constituents (typically solids or unwanted signal components) from a continuous input stream, producing a cleaned output stream.

The differentia captures that filters perform a specialized type of separation - selective removal based on barriers, size, or other discriminating properties. This distinguishes them from centrifuges (force-based), scrubbers (absorption-based), or bulk separators (phase-based). The SelectiveRemovalFunction is a subtype of SeparationFunction that specifies the discriminating nature of filtration.
4 Necessary PartsPartes Necessárias

No necessary parts recorded.

These are the minimal essential parts that any filter must possess - a filtering element to perform the separation and a housing to contain and direct the process. More complex filters will have additional components (cleaning mechanisms, differential pressure indicators, etc.) but these two are universal.

TransformationTransformação
selective constituent removal - physical separation of unwanted components from fluid stream based on discriminating properties
Filters transform a contaminated input stream into a cleaned output stream plus separated waste/retained material. Unlike bulk separators that separate phases, filters selectively remove specific constituents while preserving the primary fluid phase.
Disjoint WithDisjunto com
Pump Compressor HeatExchanger
C4: Pump, Compressor, HeatExchanger. Filters have incompatible process signatures with pumps (no energy addition), compressors (no compression), and heat exchangers (no thermal transformation). The selective removal transformation is distinct from energy transfer, compression, or thermal processes.
