General Information

TF7B0.9D-85WT is manufactured as the equivalent, replacement, alternative, retrofit and analogue to Veolia Suez ZW700B-RMS UF membrane module.
TF7B0.9D-85WT ultrafiltration membrane modules are used for production of process water, potable water and wastewater. Major applications are the filtration of surface water, potable water, seawater and industrial wastewater. TF7B0.9D-85WT 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 modification technology, which makes TF7B0.9D-85WT ultrafiltration membrane modules the most robust PES (polyethersulfone) 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
• Independent module for flexible coupling
• Typical filtrate quality SDI < 2.5, 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
• Flexibility for system design with less assembly work
• Economical equivalent module for direct replacement for Veolia Suez ZW700B-RMS to fit in existing bottom frames and skids

Applications

• Surface water
• Potable water
• Seawater desalination
• Pre-treatment of industrial water
• Industrial wastewater
