Introduction:
The LEFILTER ultrafiltration (UF) modules are made from high strength, hollow fiber membranes that have excellent features and benefits:
• 0.03 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 longer 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 helps 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 capacities of 50 m3/hr (220 gpm) or less. The shorter, 60 inch length module offers higher efficiencies over a wider range of feed water conditions compared to longer length modules. The smaller, 6 inch diameter module allows a more compact design for space constrained installations.
LEFILTER Ultrafiltration Modules can be used for a wide variety of treatment applications such as surface water, seawater, industrial wastewaters, and secondary effluent wastewater.
