NM-UF-2860 Ultrafiltration Modules

The Hinada Ultrafiltration (UF) modules are made from high strength, hollow fiber membranes that have excellent features and benefits:

• 06 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 strength and chemical resistance allows long membrane life
• Hydrophilic PVDF fibers for easy cleaning and wettability that help maintain long term performance
• Outside In flow configuration for high tolerance to feed solids that help reduce the need for pretreatment processes
• U-PVC housing, helping to eliminate the need for costly pressure vessels

This module is an ideal choice for systems with capacities greater than 20 m3/hr (88 gpm). The larger, 9 inch diameter module offers the highest effective membrane area of the Hinada UF modules, which contributes to a more economical membrane system design. The shorter, 60 inch length module offers higher efficiencies over a wider range of feed water conditions compared to longer length modules.

Hinada Ultrafiltration Modules can be used for a wide variety of treatment applications such as surface water, seawater, industrial wastewaters, and secondary effluent wastewater.

Important information

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 or contact with Hinada Water Treatment.
