SHUIYI: Built on Experience, Engineered to Master Water

SHUIYI TIPS ultrafiltration membrane technology is becoming an effective approach for improving flux, membrane durability, and fouling resistance in demanding water treatment applications. As water treatment systems face increasingly complex feed water conditions and higher requirements for treatment efficiency, ultrafiltration membrane performance has become an important factor in system design and operation.

Conventional ultrafiltration membranes may face challenges such as limited operating flux, membrane fouling, frequent chemical cleaning, fiber breakage, and high membrane requirements.

Leveraging proven Thermally Induced Phase Separation (TIPS) membrane fabrication technology, SHUIYI Membrane Technology has developed a new TIPS Process Pressurized Ultrafiltration Membrane designed to deliver high flux, high mechanical strength, excellent chemical resistance, and superior anti-fouling performance.

The membrane is designed to provide a flexible solution for existing ultrafiltration systems while helping water treatment systems improve water production capacity, reduce system footprint, and optimize lifecycle operating costs.

What Is TIPS Ultrafiltration Membrane?

Compared with conventional NIPS (Non-solvent Induced Phase Separation) ultrafiltration membranes, the TIPS process enables the development of membrane structures with improved pore connectivity and mechanical properties.

For water treatment applications, these structural characteristics can contribute to:

• Higher membrane permeability
• Higher operating flux
• Stronger membrane fibers
• Better resistance to mechanical stress
• Excellent chemical cleaning resistance
• Improved resistance to membrane fouling

For applications where treatment capacity, footprint and long-term operating stability are important, TIPS technology provides an alternative approach to conventional Ultrafiltration membrane solutions.

Compared with NIPS ultrafiltration membranes, TIPS ultrafiltration membranes deliver over 100% improvement in overall performance.

01. SHUIYI TIPS Ultrafiltration Membrane: High Flux Performance

One of the key advantages of the SHUIYI TIPS ultrafiltration membrane is its high permeability.

Pure Water Flux: 1,500–2,500 LMH

The highly porous membrane structure enables a pure water flux of approximately 1,500–2,500 LMH.

Compared with conventional NIPS ultrafiltration membranes, the supplied product material states that TIPS ultrafiltration membranes can achieve more than 100% improvement in overall performance, while the higher flux can reduce the required membrane area by more than 30% for the same application.

A higher operating flux can potentially help water treatment systems achieve:

• Smaller membrane installation areas
• Reduced equipment footprint
• Lower civil construction requirements
• Reduced membrane quantity
• More compact system design

This makes high-flux TIPS ultrafiltration membranes particularly suitable for water treatment systems where space and treatment capacity are critical considerations.

02. SHUIYI TIPS Ultrafiltration Membrane:Extended Service Life

• Excellent Chemical Cleaning Recoverability:
  Under high-fouling conditions, the membrane can withstand strong acid and alkali chemical cleaning across a pH range of 1–14, enabling effective recovery of membrane performance.
• High Mechanical Strength:
  With excellent mechanical strength, the membrane can withstand greater mechanical impact and stress during operation, significantly reducing fiber breakage.

• Superior Chemical Resistance:
  Excellent chemical resistance across a wide pH range of 1-14 enables the membrane fibers to withstand frequent acid and alkali cleaning without becoming brittle or prone to breakage.
• High Mechanical Strength:
  The fiber breaking strength of SHUIYI TIPS membranes is more than 30% higher than that of conventional NIPS membranes, significantly reducing the risk of fiber breakage and enabling a service life of more than twice that of conventional NIPS membranes.

03. SHUIYI TIPS Ultrafiltration Membrane:Superior Anti-Fouling Performance& Adaptability to Complex Feed Water

• Excellent Hydrophilicity：
  The membrane material features superior hydrophilicity, resulting in low permeation resistance and reduced fouling tendency.
• Combined Air-Water Backwashing：
  The air-water combined backwashing process delivers superior cleaning efficiency, enabling more thorough membrane cleaning and more effective flux recovery compared with air-only or water-only backwashing.

• Permanent Hydrophilicity:
  A permanent hydrophilic modification technology ensures long-lasting hydrophilicity without degradation over time. This enables the membrane to maintain high operating flux under lower transmembrane pressure, while extending the flux decline cycle for longer-lasting performance.
• Combined Air-Water Backwashing:
  Enabled by the membrane’s high mechanical strength, the combined air-water backwashing process effectively removes stubborn foulants, mitigates membrane fouling, and reduces operation and maintenance costs.
