ZW700B 450

Summary

Product identification

The SUEZ ZeeWeed* Ultrafiltration (UF) model ZW700B-450/UF10/7B/S/0.9/2.65 features SevenBore* fiber technology with an inside-out flow orientation. The SevenBore fiber is a robust polyether sulfone (PES) product.

General properties:

• UF membrane for optimal removal of particulates, bacteria and viruses.
• PES membrane fibers with 7 bores provide high mechanical strength (>10x that of single fibers) and chemical resistance.
• Inside-Out filtration eliminates the need for an air scouring step and related equipment.

Storage and handling

All elements are filled with glycerin when new as part of the fiber manufacturing and preservation process. Elements must be stored in a dry and normally 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).
