General Information
Ultrafiltration membrane is a hydrophilic semi permeable membrane made by ultrafiltration technology, mainly used in water filtration or material separation.TFIMX-77P Ultrafiltration membrane is a pressurized membrane, which are designed and manufactured for the filtration of surface water, potable water, seawater, industrial wastewater and municipal sewage. These ultrafiltration membranes are made of upgraded new generation PVDF hollow fibers with extra permeability than IM series.
Ultrafiltration membrane TFIMX-77P is applied in new systems, as well as directly connected to existing ultrafiltration systems as replacements, providing high-quality filtrate by removing suspended solids, colloids, pyrogens, bacteria, viruses and other impurities to protect downstream processes.
Features
- Outside-to-inside flow direction
- Upgraded new generation PVDF hollow fiber
- Nominal pore size of 0.03 μm
- Typical filtrate quality SDI ≤ 2.5, turbidity ≤ 0.1 NTU
Advantages
- Integrated design for easy installation
- High-quality filtrate
- Less energy needed by extra high permeability
- Longer service life by high fouling resistance and mechanical strength
- Direct and economical ultrafiltration membrane replacement
Applications
- Surface water
- Potable water
- Beverage clarification
- Industrial process water
- Industrial wastewater
- Reclaimed water reuse
- Pre-treatment of sea water desalination
