| deposit | 1. That is deposited, or laid or thrown down; as, a deposit in a flue; especially, matter precipitated from a solution (as the siliceous deposits of hot springs), or that which is mechanically deposited (as the mud, gravel, etc, deposits of a river). "The deposit already formed affording to the succeeding portion of the charged fluid a basis." (Kirwan) 2. <chemical> A natural occurrence of a useful mineral under the conditions to invite exploitation. 3. That which is placed anywhere, or in any one's hands, for safe keeping; somthing intrusted to the care of another; especially, money lodged with a bank or banker, subject to order; anything given as pledge or security. 4. A bailment of money or goods to be kept gratuitously for the bailor. Money lodged with a party as earnest or security for the performance of a duty assumed by the person depositing. 5.

Depositus, p. P. Of deponere: cf. F. Depot, OF. Depost. See Deposit, and cf. Depot. Source: Websters Dictionary (01 Mar 1998) |
| activated sludge | See: activated sludge method. (05 Mar 2000) |
| 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) |
