| 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) |
