General Information

TF7B0.9D-40H is manufactured as the quivalent, replacement, alternative, retrofit and analogue to DuPont Inge dizzer L 0.9 MB 40 PB (VK-0108), which are used for production of process water and potable water. Major applications are the filtration of surface water, seawater and industrial wastewater. TF7B0.9D-40H ultrafiltration elements use Tanal’s SevBore fiber technology with an inside-out flow. SevBore fibers are naturally hydrophilic 7-bore PES hollow fibers by advanced modification technology, which makes TF7B0.9D-40H 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

The 3rd generation modified PES membrane fibers of 7 bores
A nominal pore size of 0.02 μm for optimal removal of particles, bacteria and viruses
Inside-out flow direction without air scouring
Typical filtrate quality SDI < 2.5, turbidity < 0.1 NTU

Advantages

Extremely high mechanical strength avoiding fiber breakage
High chemical tolerance
High-quality filtrate by reliable blocking of microorganisms and viruses
Minimum operating costs and efficient backwash
Economical equivalent element for direct replacement of DuPont Inge dizzer L 0.9 MB 40 PB (VK-0108) as plug-and-play

Applications

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