ZW700B-RMS
rackless module system – ZeeWeed* pressurized ultraf iltration (UF)
Description and use
As a pioneer of membrane technology, veolia leverages decades of research, development, and operational experience to offer one of the most advanced ultrafiltration technology in the market. The ZeeWeed 700B-10060
(Figure 1) line of products contains our SevenBore* fiber technology with an inside-out flow orientation.
The SevenBore fiber is regarded as a leading polyethersulfone (PES) product on the market.
Customers of pressurized UF systems want cost- effective, worry-free solutions that meet their specific needs for the lifetime of their plant. VEOLIA’s engineers have developed a revolutionary solution that meets all these needs.

general properties
• UF membrane – for optimal removal of particulates, bacteria and viruses
• PES membrane fibers with 7 bores – provides high mechanical strength (>10x that of single fibers) and chemical resistance
• Inside-Out filtration – eliminates air scouring step and additional related equipment
storage and handling
All elements are filled with glycerin when new, which is part of the fiber manufacturing and preservation process. Elements must be stored in a dry and normal ventilated location, away from any sources of heat, ignition and direct sunlight in the original packing. The storage temperature must be between 5°C and 35°C (45°F to 91°F).
