DOW Advanced Ultrafiltration Modules SFP-2880 and SFD-2880
Features
The DOW
Ultrafiltration (UF) modules are crafted from high-strength, hollow fiber membranes, boasting exceptional features and benefits:
· A nominal pore diameter of 0.03 µm for eliminating bacteria, viruses, and particulates, including colloids, to safeguard downstream processes like RO.
· PVDF polymeric hollow fibers for superior strength and chemical resistance, ensuring a long membrane lifespan.
· Hydrophilic PVDF fibers for effortless cleaning and wettability, aiding in maintaining long-term performance.
· An Outside-In flow configuration for high tolerance to feed solids, reducing the requirement for pretreatment processes.
· U-PVC housing, eliminating the need for expensive pressure vessels.
This module is an ideal selection for systems with capacities exceeding 50 m3/hr (220 gpm). Larger and longer, with an 8-inch diameter and 80-inch length, along with an increase in packing density to 10,000 fibers, this module provides the highest effective membrane area among the DOW Ultrafiltration modules. The 2880 contributes to a more cost-effective membrane system design.
DOW Ultrafiltration Modules can be utilized in a wide range of treatment applications, such as surface water, seawater, industrial wastewaters, and secondary effluent wastewater.

Proper start-up of a UF 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 product technical manual.
Avoid any abrupt pressure variations during start-up, shutdown, cleaning or other sequences to prevent possible membrane damage. Flush the UF system to remove shipping solution prior to start up. Remove residual air from the system prior to start up. Manually start the equipment. Target a permeate flow of 60% of design during initial operations. Depending on the application, permeate obtained from initial operations should be discarded. Please refer to the product technical manual.
General information
If operating limits and guidelines given in this bulletin are not strictly followed, the limited warranty (Form No. 795-00027) will be null and void.
To prevent biological growth during system shutdowns, it is recommended that preservative solution be injected into the membrane modules.
Regulatory note NSF/ANSI 61 certified drinking water modules require specific conditioning procedures prior to producing potable water. Please refer to the product technical manual flushing section for specific procedures. Drinking water modules may be subjected to additional regulatory restrictions in some countries. Please check local regulatory guidelines and application status before use and sale.
