DOW Ultrafiltration (UF) modules are crafted from PVDF hollow fiber membranes of high mechanical strength. These modules offer outstanding performance and industry-leading membrane area. They possess the following properties and characteristics:
• A 0.03 µm nominal pore diameter for the removal of bacteria, viruses, and particulates, including colloids, to safeguard downstream processes such as RO.
• PVDF polymeric hollow fibers provide high mechanical strength and chemical resistance, ensuring a long membrane life and reliable operation.
• Hydrophilic PVDF fibers facilitate easy cleaning and wettability, aiding in maintaining long-term performance.
• The Outside-In flow configuration enables 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. U-PVC housing helps eliminate the need for costly pressure vessels.
The 2860, which is shorter in length, is recommended for smaller systems and where building height is a concern. The 2880 has a higher membrane area within the same footprint, providing a more economical design.
DOW Ultrafiltration Modules can be utilized in a wide variety of treatment applications, such as surface water, seawater, and industrial and municipal wastewaters.

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.
