General Information
Asahi Kasei Microza UNA-620C equivalent ultrafiltration (UF) membrane module TFUNAP-50 is a pressurized integrated module, which is designed and manufactured for the filtration of surface water, potable water, seawater and industrial wastewater. These UF modules are made of upgraded new generation TIPS (thermally induced phase separation) PVDF hollow fibers with high tensile strength and extra permeability.
Features
- Outside-to-inside flow direction
- New generation TIPS PVDF hollow fiber
- Uniform pore size of 0.1 μm
- Typical filtrate quality SDI ≤ 2.5, turbidity ≤ 0.1 NTU
Advantages
- Upgraded design for easy installation
- High-quality filtrate
- Less energy needed by extra high permeability
- Longer service life by high mechanical strength and fouling resistance
- Economical equivalent module for direct replacement of Asahi Kasei Microza UNA-620C
Applications
- Surface water
- Potable water
- Beverage clarification
- Reclaimed water reuse
- Industrial wastewater
- Pre-treatment of seawater desalination
