Speciality filter bags – technical overview
Speciality filter bags are selected for specific filtration challenges where standard felt, monofilament or extended life filter bags are not sufficient. These bags typically use niche media, functional layers or special constructions to address defined contamination or process requirements.
Filtration approach
Unlike general-purpose filter bags, speciality filter bags are usually selected based on a specific performance requirement rather than a generic filtration duty. Selection is often project-driven and depends on the process fluid, contaminant type and required functional behaviour.
Types of speciality filter bags
- POMF filter bags – designed for targeted filtration duties using specialised media constructions
- BOSG filter bags – selected for specific industrial applications requiring defined structural or functional properties
- Oil absorption filter bags – engineered to selectively absorb oils and hydrocarbons from aqueous streams
- X100 filter bags – application-specific designs selected for particular filtration challenges
Performance characteristics
- Application-specific behaviour – designed to address defined contaminants or process needs
- Functional media – specialised fibres or constructions beyond standard depth or surface filtration
- Project-based selection – often selected in consultation based on operating conditions
Typical applications
- Oil and hydrocarbon removal from process or wastewater streams
- Industrial filtration challenges requiring niche media solutions
- Processes where standard filter bag constructions are not suitable
- Project-based filtration solutions for specific fluids or contaminants
Key selection criteria
- Process fluid composition and operating conditions
- Contaminant type (e.g. oil, gels, fines, mixed solids)
- Required functional performance rather than micron rating alone
- Bag size, sealing configuration and housing compatibility
- Target run time and operational constraints
Speciality filter bags are often selected alongside standard filtration solutions as part of a broader filtration strategy, rather than as a direct replacement for general-purpose filter bags.
Depending on the application, speciality filter bags may be used in combination with felt filter bags, extended life filter bags or absolute filter bags as part of a multi-stage filtration process.
