The process by which organic or volatile matter and sludge is gasified, liquefied, mineralized or converted into more stable organic matter through the activity of living organisms, which Includes aerated holding tanks; (45) Sludge Drying Beds. An area comprising natural or artificial layers of porous materials upon which digested sewage sludge is dried by drainage and evaporation; (46) Sludge Eiutriatlon. A process of sludge conditioning in which certain constituents are removed by suocessive washings with fresh water or plant effluent; (47) Sludge Gas 011izationt. The process of using sewage gas for the purpose of heating buildings, driving engines, etc.; (48) Sludge Holding Tank (Aerated and Nonaerated). A tank utilized for small wastewater treatment plants not containing a digester In which sludge may be kept fresh, and supernatant withdrawn prior to a drying method (i.e. sludge drying bads); This may be done by adding a small amount of air simply to keep the sludge fresh, but not necessarily an amount that would be required to achieve stabilization of organic matter. A nonaeraled tank would simply be used to decant sludge prior to dewatering and would not allow long periods (several days of detention) without resuitIng odor problems; (49) Sludge Incinerators. A furnace designed to bum sludge and to remove all moisture and combustible materials and reduce the sludge to a sterile ash; (50) Sludge Stabilization (Chemical or Thermal). A process to make treated sludge less odorous and putrescibie, and to reduce the pathogenic organism content; This may be done by pH adjustment, chlorine dosing, or by heat treatment; (51) Sludge Thickener. A type of sedimentation tank In which the sludge Is permitted to settle and thicken through agitation and gravity; (52) Slabilizatiort lagoon A type of oxidation lagoon in which biologicat oxidation of organic matter Is effected by natural transfer of oxygen to the water from air (not a polishing pond); (53) Stand -By Power Supply. On site or portable electrical generating equipment; (54) Static Screens. A stationary screen designed to remove solids, including non biodegradable particulate (floatabie solids, suspended solids and BOD reduction) from municipal and industrial wastewater treatment systems; (55) Tertiary Treatment. A stage of treatment following secondary which is primarily for the purpose of effluent polishing; A settling lagoon or sand or coal fiber might be employed for this purpose; (56) Thermal Pollution Control Device. A device providing for the transfer of heat from a fluid flowing In tubes to another fluid outside the tubes, or vice versa; or other means of regulating liquid temperatures; (57) Thermal Sludge Conditioner. A conditioning process by which heat Is added for a protracted period of time to Improve the dewalerabilhy of sludge by the solubilizing and hydrauflzing of the smaller and more highly hydrated sludge particles; (58) Toxic Materials. Those wastes or combinations of wastes, Including dEssasa-causing agents which after discharge and upon exposure, Ingestion, Inhalation or assimilation into any organism, either directly from the environment or indirectly by ingestion through food chains, will cause death, disease, behavioral abnormalities. cancer, genetic mutations, physiological malfunctions (including malfunctions In reproduction) or physical deformations, in such organisms or their Offspring; Toxic materials Include, by way of illustration and not limitation: lead, cadmium, chromium, mercury, vanadium, arsenic, zinc, orlho•riltro-ohlorobenzene (ONCE), polychlodnaled blphenyts (PCBs) and d€chlorodrphenyl ldch€oroathane (DDT); and any other materials that have or may hereafter be determined to have toxic properties; (59) Trickling Filter. A biological treatment unit consisting of a material such as broken done or rock over which wastewater is distributed; A high rate trickling filter Is one which operated at between 10 and 30 mgd per acre. A low rate trickling filter Is one which is designed to operate at one to lour mgd per acre; (60) Trickling Ffter (Packed Tower). A plug flow type of operation In which wastewater flows down through successive layers of media or filtrate material; Organ. material Is removed continually by the active biological fixed growth in each successive layer. This method may produce "secondary" qualify effluent, or may be adapted to produce s nitrilied effluent; (61) vacuum (ffter, Centrifuges, or Fifer Presses. Devices which are designed to remove excess wafer from either digested or undigested sludge prior to disposal or further treatment.
