  2. Stabilized liquid membrane device - Wikipedia

    en.wikipedia.org/wiki/Stabilized_Liquid_Membrane...

    The stabilized liquid membrane device (SLMD) is a passive, integrative sampler that provides an alternative or complementary approach to the conventional water sampling of aqueous metals. The simple device is composed of nonporous low-density plastic lay-flat tubing, which is filled with a chemical mixture containing a chelating agent (metal ...

  3. Synthetic membrane - Wikipedia

    en.wikipedia.org/wiki/Synthetic_membrane

    An artificial membrane, or synthetic membrane, is a synthetically created membrane which is usually intended for separation purposes in laboratory or in industry. Synthetic membranes have been successfully used for small and large-scale industrial processes since the middle of the twentieth century. [ 1 ]

  4. Membrane technology - Wikipedia

    en.wikipedia.org/wiki/Membrane_technology

    Membrane technology encompasses the scientific processes used in the construction and application of membranes. Membranes are used to facilitate the transport or rejection of substances between mediums, and the mechanical separation of gas and liquid streams.

  5. Thin-film composite membrane - Wikipedia

    en.wikipedia.org/wiki/Thin-film_composite_membrane

    NanoH2O Inc. commercialized a membrane in which zeolite nanoparticles were synthesized and embedded within an RO membrane to form a thin-film nanocomposite, or TFN, which has proven to be more than 50-100% more permeable compared to conventional RO membranes while maintaining the same level of salt rejection. [12] Fuel-cells. Batteries.

    Most commercial hollow fiber membranes are packed into cartridges which can be used for a variety of liquid and gaseous separations. Schematic diagram of a hollow fiber membrane, including a view of the membrane module and call outs for a cross section (top right), membrane transport (bottom left) and partial pressure of the solute.

  7. Membrane distillation - Wikipedia

    en.wikipedia.org/wiki/Membrane_distillation

    Membranes used for membrane distillation (MD) inhibit passage of liquid water while allowing permeability for free water molecules and thus, for water vapour. [1] These membranes are made of hydrophobic synthetic material (e.g. PTFE, PVDF or PP) and offer pores with a standard diameter between 0.1 and 0.5 μm (3.9 × 10 −6 and 1.97 × 10 −5 ...

  9. Membrane gas separation - Wikipedia

    en.wikipedia.org/wiki/Membrane_gas_separation

    The membrane channels consists of cavities and windows. The energy of the molecules in the cavity is U c and the energy of a particle in the window is U w. Nanoporous membranes are fundamentally different from polymer-based membranes in that their chemistry is different and that they do not follow the Robeson limit for a variety of reasons.
