• Emerging Contaminants: PFOS AND PFOA
    Emerging Contaminants: PFOS AND PFOA

    PFCS are manmade fully fluorinated compounds which are not naturally found in the environment, are used in a variety of products such as fire fighting foams, coating additives as a surface-activeagent. PFOS (perfluorooctane sulfonate) and PFOA (Perfluorooctanoic acid) are the most commonly produced PFCs, and large amounts of PFCs have been produced during past manufacturing processes and released to the air, soil and water.

  • SEPAREL PF Series
    SEPAREL PF Series

    The PF-F degasification mechanism removes gases dissolved in liquids through a tube-shaped gas-permeable membrane made of polytetrafluoroethylene (PTFE). Specifically, gases dissolved in the liquid flowing through the tube are removed by the pressure difference of the gases inside and outside of the tube created by a vacuum on the outside of the tube as shown in the diagram below. Watch this video to see how the process works.

  • SEPAREL EF Series
    SEPAREL EF Series

    Because liquid randomly flows over the hollow fibers during external perfusion, dissolved gasses touch the membrane more frequently. Therefore, degasification performance is higher than in the Internal Perfusion Series (PF Series). Also, a lower pressure drop means that larger modules can be used. Watch this video to see how the process works.
