Membrane technology

<p>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. In the simplest case, filtration is achieved when the pores of the membrane are smaller than the diameter of the undesired substance, such as a harmful microorganism. Membrane technology is commonly used in industries such as water treatment, chemical and metal processing, pharmaceuticals, biotechnology, the food industry, as well as the removal of environmental pollutants.
</p><p>After membrane construction, there is a need to characterize the prepared membrane to know more about its parameters, like pore size, function group, material properties, etc., which are difficult to determine in advance. In this process, instruments such as the <a href="/facts/Scanning_electron_microscope/yzK0hsSx">Scanning Electron Microscope</a>, the <a href="/facts/Transmission_electron_microscopy/Rpr8jpCn">Transmission electron Microscope</a>, the <a href="/facts/Fourier_Transform_Infrared_Spectroscopy/G9UscTuA">Fourier Transform Infrared Spectroscopy</a>, <a href="/facts/X-ray_Diffraction/V2kxuumq">X-ray Diffraction</a>, and Liquid–Liquid Displacement Porosimetry are utilized.
