|---|---|
| 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) |
| androgens, synthetic | Compounds obtained by chemical synthesis which possess masculinizing activities, but differ in structure from naturally occurring androgens. (12 Dec 1998) |
| vaccines, synthetic | Small synthetic peptides that mimic surface antigens of pathogens and are immunogenic, or vaccines manufactured with the aid of recombinant DNA techniques. The latter vaccines may also be whole viruses whose nucleic acids have been modified. (12 Dec 1998) |
| genes, synthetic | Biologically functional sequences of DNA chemically synthesised in vitro. (12 Dec 1998) |
| glucocorticoids, synthetic | <chemical> Synthetic chemical compounds which increase gluconeogenesis, raising the concentration of liver glycogen and blood sugar, but differ in structure from naturally occurring glucocorticoids. Pharmacological action: steroidal anti-inflammatory agents, topical anti-inflammatory agents. (12 Dec 1998) |
| resins, synthetic | Polymers of high molecular weight which at some stage are capable of being molded and then harden to form useful components. (12 Dec 1998) |
| mineralocorticoids, synthetic | Synthetic steroids that mimic the activity of the mineralocorticoids obtained from the adrenal cortex, but differ in structure from the naturally occurring mineralocorticoids. (12 Dec 1998) |
| contraceptives, oral, synthetic | Oral contraceptives which owe their effectiveness to synthetic preparations. (12 Dec 1998) |
| contraceptives, postcoital, synthetic | Postcoital contraceptives which owe their effectiveness to synthetic preparations. (12 Dec 1998) |
| progestational hormones, synthetic | Compounds obtained by chemical synthesis that possess progestational activity, but differ in structure from naturally occurring progestational hormones. (12 Dec 1998) |
| prostaglandin endoperoxides, synthetic | Synthetic compounds that are analogs of the naturally occurring prostaglandin endoperoxides and that mimic their pharmacologic and physiologic activities. They are usually more stable than the naturally occurring compounds. (12 Dec 1998) |
