The choice of membrane material greatly affects filtration efficiency, compatibility, and longevity. Commonly used membrane materials include:
PTFE (Polytetrafluoroethylene): Chemically inert and highly resistant to aggressive solvents and acids. Ideal for gas and aggressive liquid filtration.
PES (Polyethersulfone): Offers low extractables and fast flow rates. Suitable for high-purity water and biological fluids.
PVDF (Polyvinylidene Fluoride): Excellent chemical resistance and mechanical strength. Often used in wet processes.
Nylon (Polyamide): Good for general-purpose applications but not suitable for strongly acidic environments.
Polypropylene (PP): Cost-effective, broad chemical compatibility. Often used as a pre-filter or in less demanding applications.
Membrane selection depends on the specific process requirements, including fluid type, operating temperature, pH range, and required retention efficiency.
Micron rating is a critical factor in determining filtration performance. In microelectronics, even sub-micron particles can cause defects in wafers or reduce yield rates.
Key Considerations:
Nature of the Contaminant: Particle size and composition help determine the required retention size.
Application Stage: Use coarser filters for pre-filtration (e.g., 5-10 µm) and finer filters (e.g., 0.1-0.2 µm) for final polishing.
Fluid Viscosity: More viscous fluids may require larger micron ratings to maintain flow rates.
System Pressure: Finer filters increase pressure drop; balance filtration precision and energy consumption.
Typical Micron Ranges:
UPW Systems: 0.1 to 0.2 µm
Chemical Filtration: 0.05 to 0.45 µm, depending on purity requirements
CMP Slurries: 0.5 to 1 µm
Proper micron selection ensures product quality and prevents costly equipment downtime.
The filter housing holds and seals the cartridge during operation. A well-designed housing ensures leak-free performance and system compatibility.
Selection Criteria:
Material Compatibility: Common materials include SS316L, PVDF, and polypropylene. Choose based on fluid type and temperature.
Pressure Rating: Ensure the housing withstands system operating pressures with a safety margin.
Connection Type: Sanitary, flange, or threaded connections depending on plant layout and compliance requirements.
Cartridge Configuration: Verify compatibility with 222/Flat, 222/Fin, or DOE end caps.
Ease of Maintenance: Quick-release clamps or swing bolts reduce downtime during filter change-out.
Housing Capacity: Choose single-round or multi-round configurations based on flow demand and footprint.
High-purity applications often use housings certified to ASME BPE, FDA, or USP standards.
Certifications ensure filter performance, safety, and compliance with industry regulations. Important certifications include:
ISO 9001: Demonstrates quality management systems.
FDA Compliance: Ensures materials are safe for use with food and pharmaceuticals.
USP Class VI: Confirms biological safety of materials.
NSF/ANSI Standards: Applicable to water purification components.
ASME BPE Compliance: Relevant for bio/pharma-grade systems.
RoHS Compliance: Restricts hazardous substances.
BFE (Bacterial Filtration Efficiency): Important for gas or air filtration in sterile environments.
Integrity Testing Certifications: Verifies retention and pore size through bubble point or diffusion tests.
Purchasing filters with the right certifications ensures regulatory compliance and supports quality assurance systems.
