DOW™ Ultrafiltration (UF) Modules
DOW™ ultrafiltration modules utilize high-strength hollow fiber membranes, offering the following key features and benefits:
Nominal Pore Size: 0.03 µm pores effectively remove bacteria, viruses, and particulates, including colloids, to protect downstream processes like reverse osmosis (RO).
Durable Materials: Polyvinylidene fluoride (PVDF) hollow fibers provide exceptional strength and chemical resistance, prolonging membrane life.
Easy Cleaning: Hydrophilic PVDF fibers allow for easy cleaning and wetting, maintaining long-term performance.
Efficient Flow Configuration: The outside-in flow configuration accommodates high tolerance to feed solids, reducing the need for extensive pre-treatment processes.
Cost-Effective Design: U-PVC housing eliminates the need for expensive pressure vessels.
These UF modules are ideal for systems with capacities greater than 50 m³/hr (220 gpm). The larger 8-inch diameter modules feature the highest active membrane area of any DOW UF module, optimizing system design. The shorter 60-inch length modules offer enhanced efficiency across a broader range of influent conditions compared to longer modules.
Applications: DOW™ UF modules can be used in a variety of water treatment applications, including:
Surface water, seawater, industrial wastewater, and secondary effluent treatment
Pre-treatment for reverse osmosis systems to reduce Total Cost of Ownership (TCO)
Wastewater reclamation to increase water availability in regions with limited resources
Additional Applications Include:
Food & Beverage: Clarification of juices, wines, and beer; production of milk and cheese
Microelectronics: Production of ultrapure water for manufacturing processes
Life Sciences: Pharmaceutical manufacturing, biotechnology (protein purification), and medical applications (blood filtration)
Ultrafiltration membranes effectively address challenges like membrane fouling, reducing energy consumption and chemical use while extending membrane service life. This translates into lower operational costs and improved system reliability.
