  2. Ultrafiltration - Wikipedia

    en.wikipedia.org/wiki/Ultrafiltration

    Ultrafiltration (UF) is a variety of membrane filtration in which forces such as pressure or concentration gradients lead to a separation through a semipermeable membrane. Suspended solids and solutes of high molecular weight are retained in the so-called retentate, while water and low molecular weight solutes pass through the membrane in the ...

    en.wikipedia.org/wiki/Membrane_technology

    The dead-end membrane separation process is easy to implement and the process is usually cheaper than cross-flow membrane filtration. The dead-end filtration process is usually a batch -type process, where the filtering solution is loaded (or slowly fed) into the membrane device, which then allows passage of some particles subject to the ...

  4. Membrane fouling - Wikipedia

    en.wikipedia.org/wiki/Membrane_fouling

    Membrane fouling is a process whereby a solution or a particle is deposited on a membrane surface or in membrane pores in a processes such as in a membrane bioreactor, [1] reverse osmosis, [2] forward osmosis, [3] membrane distillation, [4] ultrafiltration, microfiltration, or nanofiltration [5] so that the membrane's performance is degraded.

  5. Pervaporation - Wikipedia

    en.wikipedia.org/wiki/Pervaporation

    The term pervaporation is a portmanteau of the two steps of the process: (a) permeation through the membrane by the permeate, then (b) its evaporation into the vapor phase. . This process is used by a number of industries for several different processes, including purification and analysis, due to its simplicity and in-line natu

  6. Permeation - Wikipedia

    en.wikipedia.org/wiki/Permeation

    The process of permeation involves the diffusion of molecules, called the permeant, through a membrane or interface. Permeation works through diffusion; the permeant will move from high concentration to low concentration across the interface. A material can be semipermeable, with the presence of a semipermeable membrane. Only molecules or ions ...
