|---|---|
| activated sludge method | A method of sewage disposal in which the sewage is treated with 15% bacterially active, liquid sludge, which is produced by repeated vigorous aeration of fresh sewage to form floccules or sediment; when this flocculation process is complete, the resulting activated sludge contains large numbers of bacteria, together with yeasts, molds, and protozoa, which actively effect the oxidation of organic compounds; this mixture is piped to a sedimentation tank, the effluent from which is completely treated sewage. (05 Mar 2000) |
| activated sludge process | <procedure> A method of treating sewage and wastewater through microbial oxidation. Sewage previously treated in settling tanks is aerated to encourage the growth of nonpathogenic aerobic microorganisms (bacteria, yeasts, moulds and protozoans) which break the organic matter down into carbon dioxide, water and simple salts. After this activated sludge is produced, the wastewater undergoes further processing through anaerobic digestion, filtering and chlorination. (29 Dec 1997) |
| sludge | 1. Mud; mire; soft mud; slush. 2. Small floating pieces of ice, or masses of saturated snow. 3. <chemical> See Slime. Sludge hole, the hand-hole, or manhole, in a steam boiler, by means of which sediment can be removed. Origin: CF. Slush. Source: Websters Dictionary (01 Mar 1998) |
|---|---|
| upflow sludge blanket | <apparatus> An apparatus for anaerobic digestion in which the microbes form thick flocculations that are kept suspended near the bottom of the reaction tank. (09 Oct 1997) |
| activated acetaldehyde | The activated form of acetaldehyde that is formed during the decarboxylation of active pyruvate. Formed in alcohol fermentation and in carbohydrate metabolism. Synonym: a-hydroxyethylthiamin pyrophosphate. (05 Mar 2000) |
| activated amino acid | The product formed by the condensation of the acyl radical of an amino acid and adenosine 5'-monophosphate (originally in the form of adenosine 5'-triphosphate, with elimination of a pyrophosphoric group). Formed in the first step of protein biosynthesis. Synonym: activated amino acid. (05 Mar 2000) |
| activated atom | An atom possessing more than normal energy as a result of input of energy. See: excited state. Synonym: excited atom. (05 Mar 2000) |
| activated carboxylic acid | Derivative of a carboxyl group that is more susceptible to nucleophilic attack than a free carboxyl group; e.g., acid anhydrides, thioesters. (05 Mar 2000) |
| activated charcoal | <drug> A type of carbon produced through exposing a source material such as wood or bone to very high temperatures in the presence of steam, air or carbon monoxide. Activated carbon is very good at removing (adsorbing) contaminants and is used in water filters, to decolour solutions and is sometimes administered to poisoning victims. (15 Jan 1998) |
| activated choline | An intermediate in the formation of phosphatidylcholine (lecithin); formed by the action of cytidine 5'-triphosphate on phosphocholine, linking the choline phosphate group to the alpha-phosphate of the cytidine 5'-triphosphate to give a pyrophosphate. Synonym: activated choline, cytidine diphosphate choline. (05 Mar 2000) |
| activated clotting time | The most common test used for coagulation time in cardiovascular surgery. (05 Mar 2000) |
| activated complex | <chemistry> State of highest energy during a reaction. When reactants form the activated complex, bond breaking and bond formation is occurring. Synonym: transition state. (09 Jan 1998) |
| activated fatty acid | A fatty acyl-coenzyme A thiol ester. (05 Mar 2000) |
| activated glucose | A nucleoside diphosphoglucose such as UDP glucose. (05 Mar 2000) |
| activated macrophage | A mature macrophage, in an active metabolic state, that is cytotoxic to tumour/target cells, usually following exposure to certain cytokines. Synonym: armed macrophage. (05 Mar 2000) |
| activated partial thromboplastin time | The time needed for plasma to form a fibrin clot following the addition of calcium and a phospholipid reagent; used to evaluate the intrinsic clotting system. (05 Mar 2000) |
| activated resin | Autopolymerizing resin, any resin that can be polymerised by chemical catalysis rather than by the application of heat; used in dentistry for dental restoration, denture repair, and impression trays. Synonym: activated resin, cold cure resin, cold-curing resin, quick cure resin, self-curing resin. (05 Mar 2000) |
| activated sludge |
sludge from aerated sewage, consisting mainly of aerobic bacteria (eg, Sphaerotilus, Zoogloea), protozoa (eg, Opercularia, Vorticella), yeasts, and molds. Further treatment consists of anaerobic digestion. A portion serves as inoculum for a succeeding batch of screened and sedimented raw sewage.

| activated sludge |
Activated sludge is a process in sewage treatment in which air or oxygen is forced into sewage liquor to develop a biological floc which reduces the organic content of the sewage. In all activated sludge plants, once the sewage has received sufficient treatment, excess mixed liquor is discharged into settling tanks and the supernatant is run off to undergo further treatment before discharge. ...

| activated sludge |
Sludge particles produced in raw or settled wastewater (primary effluent) by the growth of organisms (including zoogleal bacteria) in aeration tanks in the presence of dissolved oxygen. The term "activated" comes from the fact that the particles are teeming with fungi, bacteria, and protozoa. Activated sludge is different from primary sludge in that the sludge particles contain many living organisms which can feed on the incoming wastewater.
