Hemodialysis
• UF membranes used in dialyzers to treat patients with renal failure
• The dialyzer performs the following functions:
• Rid the body of wastes, such as urea, from the blood
• Restore the proper balance of electrolytes in the blood
• Eliminate extra fluid from the body
• Sulfone polymers (PSU, PESU) are utilized thanks to:
• Tailored grades compatible with PVP • Medical Approvals ASTM F702-10 and
ISO 10993• Ability to form fine UF hollow fiber
membranes with high manufacturing productivity

• Membrane cartridges are utilized in several filtrationpurposes for high end applications such as biopharma, electronic industry, highly polluted industrial wastewater treatment, air particulate and hot air filtration
• These end uses requires high chemical andtemperature resistance due to the harsh conditionsof use and/or cleaning
