DuPont DOW UF Membrane SFD-2880XP

Features

The DuPont DOW UF Membrane SFD-2880XP modules provide excellent performance, industry leading membrane area with low energy and chemical consumption and have the following general properties and characteristics:
  • Up to 35% higher permeability than previous generation modules helping to improve operating efficiencies and productivity
  • 0.03 µm nominal pore diameter for removal of bacteria, viruses, and particulates including colloids to protect downstream processes such as RO
  • PVDF polymeric hollow fibers for high mechanical strength with excellent chemical resistance providing long membrane life and reliable operation
  • Outside-In flow configuration allowing a wide range of solids in the feed water minimizing the need for pretreatment processes and reducing the backwash volume compared to Inside-Out configurations
These modules are an excellent choice for systems with capacities greater than 50 m3 /hr (220 gpm). The SFP-2860XP modules are well suited for installations with limited height. Larger and longer, 8 inch diameter and 80 inch in length, the SFD-2880XP modules offer a high effective membrane area combined with high permeability that provides the most economical and efficient membrane system design.
DuPont DOW UF Membrane SFD-2880XP Modules can be used for a wide variety of treatment applications such as industrial and municipal wastewaters, surface water, and seawater.

Important information
Proper start-up of an ultrafiltration system is essential to prepare the membranes for operating service and to prevent membrane damage. Following the proper start-up sequence also helps ensure that system operating parameters conform to design specifications so that system water quality and productivity goals can be achieved. Before initiating system start-up procedures, membrane pretreatment, installation of the membrane modules, instrument calibration and other system checks should be completed.
Operation guidelines

Avoid any abrupt pressure variations during start-up, shutdown, cleaning or other sequences to prevent possible membrane damage. Flush the ultrafiltration system to remove shipping solution prior to start-up. Remove residual air from the system prior to start-up. Manually start the equipment. Depending on the application, filtrate obtained from initial operations should be discarded.

General information

If operating limits and guidelines given in this bulletin are not strictly followed, the limited warranty will be null and void.
To control biological growth during extended system shutdowns, it is recommended that storage solution be injected into the membrane modules.
