KH-UF-SFX2880 Ultra-filtration Membrane System for Pure Water Purification with PVDF 0.03um pore size
The SFX series of the ultrafiltration modules are built with robust outside-in PVDF fiber technology. The hollow fibers feature high clean-ability, low chemical consumption, high recovery, and a superior combination of mechanical properties and chemical resistance. It offers customers a proven product with a long list of installations world-wide.
Advantages
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.

FEATURES
The Ultrafiltration (UF) modules are made from high strength, hollow fiber membranes that have excellent features and benefits:
This module is an ideal choice for systems with capacities greater than 50 m³/hr (220 gpm). Larger and longer, 8 inch diameter and 80 inch in length, together with an increase in packing density of 10,000 fibers, this module offers the highest effective membrane area of the ultrafiltration modules. The 2880 contributes to a more economical membrane system design.
The ultrafiltration Modules can be used for a wide variety of treatment applications such as surface water, seawater, industrial wastewaters, and secondary effluent wastewater.
