Process Filtration Bags
Aris Filtration Process Filtration Bags are industrial filter bags designed to remove suspended solids, contaminants and particulate matter from process liquids and compatible industrial fluids. Available in application-specific filter media, micron ratings, sizes and fittings, they are suitable for demanding filtration processes across water treatment, chemicals, refineries, mining, oil & gas, textiles, power and other process industries.
What Are Process Filtration Bags?
Process Filtration Bags are replaceable filtration elements used inside compatible bag filter housings to separate solid particles and contaminants from industrial process liquids. The filter bag acts as the filtration medium while the housing directs the process fluid through the selected media.
Unlike a general-purpose filter bag, a process filtration bag is selected according to the fluid characteristics, particle loading, required micron rating, operating temperature, pressure, flow rate and chemical compatibility of the application.
Aris Filtration develops industrial filtration products for air, gas and liquid applications and supplies filter bags as part of its broader industrial filtration portfolio. Its existing liquid filter bag range includes PP, polyester, needle felt, nylon, monofilament, multifilament and Nomex media.
How Do Process Filtration Bags Work?
The filtration process is straightforward:
- Process fluid enters the bag filter housing.
- The fluid passes through the filter bag media.
- Suspended particles are retained by the filtration media.
- Filtered liquid exits the housing for the next process stage.
- The filter bag is replaced when its contaminant-holding capacity or permissible pressure drop is reached.
A process filtration bag separates unwanted particulate matter from a process fluid by forcing the fluid through a selected porous filtration medium.
The actual filtration performance depends on the filter media, micron rating, fluid viscosity, contaminant concentration, flow rate, pressure, temperature and housing configuration.
Which Filter Media Are Available for Process Filtration Bags?
The correct media is important because different process fluids require different levels of chemical resistance, temperature capability and particle retention.
| Filter Media | Typical Consideration | Suitable Applications |
|---|---|---|
| Polypropylene (PP) | Chemical compatibility and general liquid filtration | Water, chemicals, process liquids |
| Polyester | Industrial liquid filtration and mechanical strength | Chemicals, textiles, paints and industrial fluids |
| Nylon | Suitable for applications requiring specific media characteristics | Oils, chemicals and process liquids |
| Monofilament | Controlled surface filtration and cleanability considerations | Process liquids and particle removal |
| Multifilament | High dirt-holding applications | Industrial liquid filtration |
| Needle Felt | Depth-style particulate retention | High-solid and process liquid applications |
| Nomex | High-temperature applications where compatible | Selected demanding industrial processes |
Aris Filtration's published liquid filter bag specifications include PP, polyester, nylon and cotton construction, with stitched and welded configurations and several collar/fitting options.
What Micron Ratings and Sizes Are Available?
Filter bag selection should be based on the particle size that needs to be removed and the process requirements. Aris Filtration's published liquid filter bag range includes 1, 2, 5, 10, 25, 50, 100 and 150 micron ratings, with standard sizes such as 4" × 10", 4" × 20", 7" × 16" and 7" × 32", as well as customized configurations.
Available configurations can include:
- Different micron ratings
- Standard and customized dimensions
- PP collar
- SS ring
- Snap band
- Rubber collar
- Stitched construction
- Welded construction
The correct micron rating should be selected from actual process data rather than choosing the finest available filter by default.

Where Are Process Filtration Bags Used?
Process filtration bags can be incorporated into filtration systems across a wide range of industries where particulate removal from process fluids is required.
Water Treatment
Used for removing suspended solids and protecting downstream treatment equipment, pumps and other filtration stages.
Refineries and Oil & Gas
Process filter bags can be used for liquid filtration and equipment protection where compatible filtration media and operating conditions are selected.
Chemical and Petrochemical Plants
Filter bags can help remove particulate contamination from compatible chemicals, solvents and process liquids.
Mining and Minerals
Process filtration bags can be considered for applications involving solids-laden process streams where appropriate media and filtration capacity are required.
Pulp & Paper and Textiles
Filtration bags can be used for process-liquid filtration where removal of fibres, suspended solids and other contaminants is required.
Paints, Inks, Dyes & Intermediates
Bag filtration can help remove unwanted particulate contamination before downstream processing, filling or application.
Power Plants
Process filtration bags can support liquid filtration and equipment protection in suitable water and process-fluid applications.
Other Industries
Aris Filtration's industrial filtration portfolio is relevant to applications across edible oils, automobiles, aeronautics, cement, fertilizers, bio-pharma, ceramics, sugar, defence and marine industries, subject to process-fluid compatibility and application requirements.
What Are the Benefits of Process Filtration Bags?
The main benefits of a properly selected process filtration bag include:
- Efficient particulate removal
- High dirt-holding capacity
- High-flow liquid filtration
- Low-pressure-drop potential when correctly selected
- Easy installation and replacement
- Multiple media options
- Multiple micron ratings
- Standard and customized sizes
- Compatibility with industrial bag filter housings
- Application flexibility across different process industries
A process filtration bag should be treated as part of the complete filtration system, not as an isolated consumable.
The bag, housing, process fluid, flow conditions and contaminant load should be evaluated together for reliable filtration performance.
How Do You Select the Right Process Filtration Bag?
Before selecting a process filter bag, provide the following information:
- Type of process liquid
- Required micron rating
- Flow rate
- Operating temperature
- Operating pressure
- Particle or contaminant type
- Approximate solids loading
- Required bag dimensions
- Existing filter housing model
- Required bag fitting or collar type
For demanding applications, chemical compatibility and operating temperature should be verified before finalizing the filtration media.
