DOW™ ultrafiltration (UF) modules are made of high-strength hollow fiber membranes that offer outstanding features and benefits:
• Nominal pore size of 0.03 µm removes bacteria, viruses, and particulates including colloids to protect downstream processes such as reverse osmosis.
• Polyvinylidene fluoride (PVDF) polymer hollow fibers provide high strength and chemical resistance to extend membrane life.
• Hydrophilic PVDF fibers are easy to clean and wet, helping to maintain long-term performance.
• Outside-in flow configuration provides high tolerance to feed solids, helping to reduce the need for pre-treatment processes.
• U-PVC housing helps eliminate the need for expensive pressure vessels.
This module is ideal for systems with capacities greater than 50 m3/hr (220 gpm). The larger 8-inch diameter module offers the highest active membrane area of any DOW UF module, helping to achieve more economical membrane system design. The shorter 60-inch length modules offer higher efficiency over a wider range of influent conditions than longer modules.
DOWTM UF modules can be used in a variety of treatment applications such as surface water, seawater, industrial wastewater and secondary effluent wastewater.

Operating Parameters
Important information
Proper start-up of a UF system is indispensable for preparing the membranes for operational service and preventing membrane damage. Adhering to the correct start-up sequence also contributes to ensuring that the operating parameters of the system conform to the design specifications, thereby enabling the attainment of system water quality and productivity targets. Before commencing the system start-up procedures, membrane pretreatment, installation of the membrane modules, instrument calibration, and other system checks should be accomplished. Kindly refer to the product technical manual.
Operation guidelines
Avoid any sudden pressure fluctuations during start-up, shutdown, cleaning or other processes to prevent potential membrane damage. Flush the UF system to eliminate the shipping solution before start-up. Remove the residual air from the system before start-up. Manually initiate the equipment. Aim for a permeate flow of 60% of the design during the initial operations. Depending on the application, the permeate obtained from the initial operations should be disposed of. Please refer to the product technical manual.
Regulatory note
NOTICE: NSF/ANSI 61 certified drinking water modules demand specific conditioning procedures before generating potable water. Please refer to the flushing section of the product technical manual for detailed procedures. Drinking water modules might be subject to additional regulatory constraints in certain countries. Please verify local regulatory guidelines and the application status before usage and sale.
The utilization of this product does not inevitably ensure the elimination of cysts and pathogens from water. Effective reduction of cysts and pathogens depends on the complete system design as well as the operation and maintenance of the system.
