DuPont DOW UF Membrane IPD-51XP
- Product No.：IPD-51XP
Features
- Up to 35% higher permeability than previous generation modules improving 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 Innovative end-caps enable direct coupling of modules, eliminating the need for piping manifolds
The DuPont™ DOW™ UF Membrane modules IPD-51XP can be used for a wide variety of treatment applications, such as groundwater, surface water, seawater, industrial wastewaters and municipal wastewater polishing.

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. Please refer to the Ultrafiltration Technical Manual.
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.
Please refer to the Ultrafiltration Technical Manual.
General information
To control biological growth during extended system shutdowns, it is recommended that storage solution be injected into the membrane modules.
Please refer to the Ultrafiltration Technical Manual and Technical Service Bulletins.
