When selecting an ultrafiltration (UF) membrane module, performance is only one part of the equation. Equally important is manufacturing consistency and quality assurance.
A membrane module with even a minor sealing defect or damaged membrane fibers can cause leakage, unstable operation, increased maintenance costs, and unexpected downtime.
At JX Purification, every TIPS ultrafiltration membrane module is subjected to 100% factory inspection before shipment. Every single module is tested—not by sampling, but individually—to ensure reliable performance from the very first installation.
Identical construction of inner/outer surfaces/sections
Under the microscope, the structure of our TIPS membrane, both inside and outside as well as in the cross-section, can be observed. It is extremely excellent and can be comparable to the well-known Japanese brand ASAHI KASEI TIPS membrane.
Unlike many industrial products, UF membrane modules operate under continuous hydraulic pressure.
Even a tiny leakage at the sealing area or a broken membrane fiber can result in:
Internal leakage
Reduced filtration efficiency
Increased SDI of permeate
Loss of recovery
Higher operating costs
Unexpected membrane replacement
For replacement modules used in municipal water treatment, industrial process water, wastewater reuse and seawater pretreatment, customers expect the same reliability as the original manufacturer.
That is why every module leaving our factory undergoes two mandatory inspections.
The first inspection verifies the mechanical sealing performance.
Each membrane module is completely filled with clean water and pressurized to 0.3 MPa.
Our quality engineers carefully inspect:
End caps
Potting area
Housing connections
Sealing interfaces
Only modules with zero leakage are approved.
This test ensures that the module can withstand normal operating pressure without external leakage.

Our beautiful UF2880 equivalent housing. Very good quality. With 5 years warranty, 10 years lifespan.
After the hydrostatic pressure test, each module undergoes a membrane integrity inspection.
Compressed air at 0.2 MPa is introduced from the feed side.
The permeate side is connected to a transparent observation tube and monitored continuously for 2 minutes.
Acceptance Criteria:
✔ No continuous air bubbles
If continuous bubbles appear, it indicates broken membrane fibers or compromised membrane integrity.
Only modules that pass this test are released for shipment.
This inspection guarantees that every membrane bundle maintains excellent airtightness and filtration integrity.
Some manufacturers inspect only selected batches.
At JX Purification, we perform 100% inspection on every membrane module before shipment.
Every module receives:
Hydrostatic pressure leak test
Membrane integrity (air hold) test
Visual appearance inspection
Dimensional inspection
Performance verification
This quality system minimizes the possibility of field failures and provides customers with confidence in long-term operation.
Our ultrafiltration membrane modules are manufactured using TIPS (Thermally Induced Phase Separation) technology.
Compared with conventional membrane manufacturing methods, TIPS membranes provide:
High mechanical strength
Excellent chemical resistance
Uniform pore distribution
Stable filtration performance
Long service life
Superior fouling resistance
These characteristics make TIPS membranes suitable for demanding industrial applications.
Our TIPS UF membrane modules are designed as drop-in replacements for many internationally recognized brands.
