membrane unit
1Membrane bioreactor — (MBR) is the combination of a membrane process like microfiltration or ultrafiltration with a suspended growth bioreactor, and is now widely used for municipal and industrial wastewater treatment with plant sizes up to 80,000 population… …
2Membrane curvature — is the geometrical measure or characterization of the curvature of membranes. The membranes can be naturally occurring or man made (synthetic). An example of naturally occurring membrane is the lipid bilayer of cells, also known as cellular… …
3unit membrane — n the limiting membrane of cells and various organelles viewed formerly as a 3 layered structure with an inner lipid layer and two outer protein layers and currently as a fluid phospholipid bilayer with intercalated proteins * * * the trilaminar… …
4Membrane operation — or membrane process is considered like a unit operation in chemical engineering. In chemistry membrane operations utilize artificial membranes to separate mixtures. According to driving force of the operation it is possible to distinguish:… …
5Membrane technology — The membrane technology covers all process engineering measures for the transport of substances between two fractions with the help of permeable membranes. That means in general mechanical separation process for separation of gaseous or liquid… …
6Membrane potential — Differences in concentration of ions on opposite sides of a cellular membrane lead to a voltage called the membrane potential. Many ions have a concentration gradient across the membrane, including potassium (K+), which is at a high inside and a… …
7Membrane reactor — A membrane reactor is a piece of chemical equipment that combines a catalyst filled reaction chamber with a membrane to add reactants or remove products of the reaction. Chemical reactors making use of membranes are usually referred to as… …
8membrane capacitance — The electrical capacitance of a membrane. Plasma membranes are excellent insulators and dielectrics: capacitance is the measure of the quantity of charge that must be moved across unit area of the membrane to produce unit change in membrane… …
9membrane — 1. A thin sheet or layer of pliable tissue, serving as a covering or envelope of a part, as the lining of a cavity, as a partition or septum, or to connect two structures. SYN: membrana [TA]. 2. SYN: biomembrane. [L. membrana, a skin or m …
10unit membrane — The three ply, approximately 7nm wide membrane structure found in all cells, composed of a fluid lipid bilayer with intercalated proteins. The unit membrane theory carries with it the presumption that all biological membranes have basically the… …
