Membrane 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… … Wikipedia
Membrane fouling — is a process where solute or particles deposit onto a membrane surface or into membrane pores in a way that degrades the membrane s performance. It is a major obstacle to the widespread use of this technology. Membrane fouling can cause severe… … Wikipedia
Membrane emulsification — (ME) is a relatively novel technique for producing all types of single and multiple emulsions (o/w, w/o, w/w, w/o/w, o/w/o, m/w, s/o/w), e.g. for DDS (drug delivery system), solid micro carriers for encapsulation of drug or nutrient, solder… … Wikipedia
Membrane 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… … Wikipedia
Membrane 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… … Wikipedia
Membrane oxygenator — A membrane oxygenator is a device used to add oxygen to, and remove carbon dioxide from the blood. It can be used in two principal modes: to imitate the function of the lungs in cardiopulmonary bypass (CPB), and to oxygenate blood in longer term… … Wikipedia
Operation — Although there are many meanings to the word operation , in medicine it refers to a surgical procedure. To put matters more formally, an operation is an act or series of acts performed upon the body with the hand alone or by means of an… … Medical dictionary
Artificial membrane — An artificial membrane, also called a synthetic membrane, is a membrane prepared for separation tasks in laboratory and industry. Its active part, which permits selective transport of material, usually consists of polymers or ceramics, seldom… … Wikipedia
semipermeable membrane — A membrane that is selectively permeable to only one (or a few) solutes. The potential developed across a membrane permeable to only one ionic species is given by the Nernst equation for the species: this is the basis for the operation of ion… … Dictionary of molecular biology
Descemet Membrane Endothelial Keratoplasty — Die Descemet Membrane Endothelial Keratoplasty (DMEK) beschreibt eine spezielle Form der Hornhauttransplantation, die bei Erkrankungen der Hornhaut zum Einsatz kommt[1], die nur das Hornhautendothel betreffen. Bei solchen Erkrankungen, wie der… … Deutsch Wikipedia
