Frequently Asked Questions

What is a Membrane Filter Cartridge?

A membrane filter cartridge is a precision filtration device that uses polyethersulfone (PES), PTFE, PVDF, or Nylon membranes to remove particles as small as 0.02 µm from liquids. It is used in pharmaceuticals, electronics, and food & beverage industries for sterile filtration, high-purity water production, and chemical process filtration.

Filtration ratings: 0.02 µm, 0.1 µm, 0.22 µm, 0.45 µm, 1 µm, up to 90 µm depending on variant
Lengths: 10″, 20″, 30″, 40″
Membrane types: Polyethersulfone (PES), PTFE, PVDF, Nylon, PBT, Glass Fiber, PFA
Efficiency: Up to 99.99% particle removal
Quality control: 100% integrity tested before delivery

How is a Membrane Filter Cartridge classified?

Membrane filter cartridges are classified by membrane material and application grade:

By membrane material:

Polyethersulfone (PES) membrane filter cartridge — pharmaceutical sterilization, biotech, general high-purity liquid filtration
PTFE membrane filter cartridge — corrosive solvents, acids, high-temperature gas filtration
Hydrophilic PVDF membrane filter cartridge — low protein adsorption, biologics, aggressive aqueous solutions
Nylon membrane filter cartridge — aqueous solutions, mild solvents, cost-effective sterile filtration
PFA membrane filter cartridge — semiconductor ultra-pure water, aggressive chemical processes
PBT polyester membrane filter cartridge — high-temperature applications up to 120°C
Glass Fiber membrane filter cartridge — high dirt-load liquid prefiltration and gas filtration

What is the structure of a Membrane Filter Cartridge?

A membrane filter cartridge consists of four main components: outer cage (support frame), filter membrane (filtration layer), end caps (sealing), and sealing rings (gasket). All components use thermal welding without adhesives to prevent contamination.

Material compatibility:

Standard applications: Polypropylene (PP) cage and end caps
Corrosive chemicals: PVDF or PFA cage and end caps required
Chemical resistance: PP withstands general acids/alkalis but NOT strong organic solvents like acetone or chloroform
Connection / End Cap Styles: DOE (Double Open End), 222 O-ring, 222 Fin, 226 O-ring, 226 Fin. Connection style must match your filter housing — confirm before ordering. Custom configurations are available.

Why do you need a Membrane Filter Cartridge?

You need a membrane filter cartridge when raw water quality doesn’t meet purity requirements. Sources like seawater, surface water, or tap water contain particles, bacteria, and colloids that require filtration down to 0.1-1μm for pharmaceutical, electronics, or food production use.

Key benefits:

Remove bacteria and particles from 0.02 µm — suitable for pharmaceutical-grade sterile filtration
Achieve up to 99.99% particle interception efficiency
Handle corrosive chemicals across a full pH range of 1–14 (acids, alkalis, solvents)
FDA-compliant options available for food, beverage, and pharmaceutical manufacturing
Ensure batch-to-batch product quality in regulated production environments

How does a Membrane Filter Cartridge work?

Membrane filter cartridges work by applying pressure to force liquid through a multi-layer membrane with gradient pore sizes (coarse to fine). Particles larger than the rated micron size are trapped in the membrane layers, while clean liquid passes through.

Working principle:

Liquid enters under pressure (0.5-4 bar)
Gradient membrane traps particles layer by layer
Contaminants stay upstream, clean water exits downstream
Multi-layer design extends filter life

Result: Up to 99.99% particle removal with absolute-rated filtration.

For feeds with high particle loads, a melt blown filter cartridge or pleated filter cartridge is often installed upstream as a pre-filter to extend membrane service life.

What are the advantages of a Membrane Filter Cartridge?

Membrane filter cartridges offer high precision (0.1-10μm), 99.99% filtration efficiency, wide chemical compatibility (pH 1-14), and long service life. They’re 100% integrity tested, easy to install, and cost-effective for pharmaceutical, electronics, and food applications.

Key advantages:

High efficiency: 99.99% absolute-rated particle removal
Chemical resistant: pH 1-14, handles acids/alkalis/solvents
Temperature tolerant: Up to 90°C for standard variants; up to 120°C for PBT polyester membrane filter cartridges
Long lifespan: High dirt holding capacity reduces change-outs
Quality assured: 100% integrity tested before delivery
Low maintenance: Easy replacement, minimal downtime

What is the production process of a Membrane Filter Cartridge?

The production process involves 7 steps: pleating membrane material → seaming with ultrasonic welding → installing outer frame tube → cutting excess material → welding end caps → installing seal rings → packaging in clean room.

Production steps:

Pleating: Membrane material pleated to precise height and corrugation count
Seaming: Ultrasonic welding joins the middle seam (no adhesives)
Install tube: Pleated membrane inserted into outer frame
Cutting: Excess material trimmed to specification
Welding end cap: Thermal welding seals end caps
Install seal ring: Gasket installed for housing compatibility
Packaging: Sealed in plastic bags, packed in cartons

Quality control: Produced in 100,000-level clean room; 100% integrity tested for sterilizing-grade filters.
