  2. SEPAREL® PF Series
    7/29/2016

    The SEPAREL PF series removes dissolved gases in water through a tube-shaped gas permeable membrane composed of polytetrafluoroethylene (PTFE). Gasses dissolved in water flow through the tube and are removed due to the pressure difference of the gases inside and outside of the tube, thus creating a vacuum outside of the tube. This video explains how the PF series works.

  3. SEPAREL® EF Series
    7/29/2016

    The SEPAREL EF series uses external flow which allows water to randomly flow over the hollow fibers and, in turn, contact dissolved gases more frequently. Therefore, desgassing performance with the EF series is higher than the PF series which utilizes internal flow. Also, a lower pressure drop means that larger modules can be used. This video explains how the EF series works.

  4. Small SEPAREL® EF Series
    7/29/2016

    The small SEPAREL EF series is optimized to remove dissolved gases in water applications with smaller flow rates. The EF series uses external flow which allows water to randomly flow over the hollow fibers and, in turn, contact dissolved gases more frequently. Therefore, desgassing performance with the EF series is higher than the PF series which utilizes internal flow. This video explains how the EF series works.

  5. SEPAREL® Hollow Fiber Membrane Modules For Liquid Degasification And Aeration
    7/29/2016

    A proprietary technology of the DIC Corporation, SEPAREL hollow fiber membrane modules are optimized for degassing and aerating water. By utilizing an innovative surface skin layer, only gas can permeate in or out of the membrane. This video introduces the benefits of SEPAREL and where is it most commonly used.
