Product Description

Ultra-filtration Membrane System for Pure Water Purification with PVDF 0.03um pore size


 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 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 50 m3/hr (220 gpm). The larger, 8 inch diameter module offers the highest effective membrane area of the 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. Ultrafiltration modules can be used for a wide variety 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
