UltraFiltration Membrane

Ultrafiltration (UF) is an important water purification technology used for production of high-purity water. UF is effective in the removal of colloids, proteins, bacteria, pyrogens (e.g. gram-negative bacterial endotoxins), and other organic molecules larger than 0.1 - 0.2 Micron in size.
How Ultrafiltration membranes work

Basic Principles of Ultrafiltration

Ultrafiltration is a pressure-driven purification process in which water and low molecular weight substances permeate a membrane while particles, colloids, and macromolecules are filtered. The primary removal mechanism is size exclusion. A properly designed UF cartridge allows efficient rising of ionic redidue from the cleaning and rapidly returns to optimal resistivity and organic purity (see figures 1 and 2). Reagent-grade sodium hydroxide has proven to be and effective cleaning agent with the following benefits:
  • Effective bacterial destruction
  • Effective depyrogenation (endotoxin reduction)
  • Efficient destruction of organic contamination
  • Reduced occurrence of chemical by-product formation
  • Minimal residue of chemical interference
  • Economical and easy-to-use cleaning age

    How UF Membranes Look

    The UF Membranes are available in several different formats: as standard sizes 10"x2.5" and 20"x2.5" for industry-standard housings. Also available as small capsule and as inline UF cartridge with 1/4" quick connect fittings:

    10x2.5 inch UF membrane
    10"x2.5" UF Membrane
    20x2.5 inch UF membrane
