type of oxidation lagoon In which biological 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 (fioaiable 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 filter
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 tlme to Improve the dewaterability of sludge by the
so(ubilizing and hydraulizing of the smaller and more highly hydrated sludge particles;
(58) Toxic Materials. Those wastes or combinations of wastes. Including disease -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, onho-nhro-cNorobenzene
(ONCE), polychlorinated blphenyls (PCBs) and dichlorodiphenyl trichloroethhane (DDT); and any other materials that have or may hereafter be determined to have
toxic properties;
(59) Trickling Finer. A biological treatment unit consisting of a material such as broken stone or rock over which wastewater is distributed- A high rate trickling
finer is one which operated at between 10 and 30 mgd per acre. A low rate trickling finer is one which is designed to operate at one to four mgd per acre;
(60) Trickling Finer (Packed Tower). A plug flow type of operation In which wastewater flows down through successive layers of media or filtrate malarial; Organic
material is removed continually by the active biological fixed growth In each successive layer. This method may produce 'secondary- quality effluent, or may be
adapted to produce a nitrified effluent;
(61) Vacuum Finer, Centrifuges, or Filter Presses. Devices which are designed to remove excess water from either digested or undigested sludge prior to disposal
or further treatment.
