TaFlux SevBore D Series
We are upgrading the product lines of TaFlux SevBore series, so these products are not available for the moment. We will fresh our webpage and catalog once they are available again.
General Information
TaFlux SevBore D series ultrafiltration membrane modules are designed and manufactured as equivalents, which are used for production of process water, potable water and wastewater. Major applications are the filtration of surface water, potable water, seawater, industrial wastewater and municipal sewage. TaFlux SevBore D series ultrafiltration modules use Tanal’s SevBore fiber technology with an inside-out flow direction. SevBore fibers are naturally hydrophilic 7-bore PES hollow fibers by advanced ultrafiltration technology, which makes TaFlux SevBore D series ultrafiltration membrane modules the most robust PES (polyether sulfone) UF membrane on the market.The mode of operation is either dead-end or cross-flow (though cross flow mode is only used in certain circumstances), backwash (with filtrate only) at regular intervals and chemically enhanced backwash are required for the continuous operation.
Features
- A nominal pore size of 0.02 μm for optimal removal of particles, bacteria, and viruses
- Inside-out flow direction without air scouring
- PES membrane fibers of 7 bores
- Typical filtrate quality SDI < 3, turbidity < 0.1 NTU
Advantages
- Extremely high mechanical strength with no fiber breakage
- High chemical tolerance
- High-quality filtrate by reliable blocking of microorganisms and viruses
- Minimum operating costs and efficient backwash
- Direct and economical module replacement for plug-and-play
Applications
- Surface water
- Potable water
- Seawater desalination
- Pre-treatment of industrial water
- Industrial wastewater
- Municipal sewage
