All influent, effluent and in•plarrt pumps; (36) Radiation. Disinfection or sterilization process uliUzing devices emitting ultint0olet or gamma rays; (37) Reverse osmosis, A ireatmerrl process In which a heavy contaminated liquid is pressurized through a membrane forming nearly pure liquid free from suspended solids; (38) Rotating Biological Contractors. A fixed biological growth process in which wastewater flows through tanks in which a series of partially submerged circular surfaces are rotated; (39) Sand Fillers: (a) Intermittent Biological. Filtration of effluent following septic tanks, lagoons, or some other treatment process in which further biodecomposhlon is expected to produce des€red effluents; Hydraulic loading rates on those filters are computed In gpolac and have a resulting low gpmrsl (less than one); b) Recirculating biological - the same type of sand lifter as defined in Subparagraph (39) (a) of this Pula with the added capability to recycle effluent back through the sand hirer; (40) Sand or Mixed -Media F€hers. A polishing process by which effluent limits are achieved through a further reduction of suspended solids; (a) low rate -- gravity, hydraulically loaded titter with loading rates In the one to three gpmVe range; (b) high rate •- a pressure, hydraulically loaded filter with loading rates in the five gprrVsf range; At any rate, the loading rate will exceed three gprrJsf; (41) Secondary Clarifiers. A tank which follows the biological unit of ireatment plant and which has the purpose of removing sludges associated with the biological treatment units; (Q) Separate Sludge Reaoration. A par; of the contact stabilization process where the activated sludge Is transferred to a tank and aerated before retuming it 10 the contact basin; (43) Septic Tank A single story settling tank in which settled sludge is In contact with the wastewater flowing through the tank; shall not be applicable for seolic tank systems serving single family residences having capacity of 2,000 gallons or less which discharge to a nhrfficalion field; (d4) Shale digestion. The process by which organic or volatile matter and sludge is gas iied, liquefied, mineralized or converted into more stable organic matter through the activity of living organisms, which Includes aerated holding tanks; (L5) Sludge Drying Beds. An area comprising natural or artificial layers of porous materials upon which digested sewage sludge is dried by dralnaga and evaporation; (46) Sludge ESutriaiion. A process of sludge conditioning in which certain consifluorlis are removed by successive washings with fresh water or plant affluent; (47) Sludge Gas Utilization. The process of using sewage gas for the purpose of heating buildings, driv;ng engines, etc.; (A -a) Sludge Bolding Tank (Aerated and Nonasratad). A lank 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 beds); 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 stabilizatlon of organic matter. A nonaerated tank would simply be used to decant sludge prior to dawalaring and would not allow long periods (several days of detention) without resulting 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 putrescible, 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 permi3led to settle and thicken through aghafion and gravity; (52) Stabilization lagoon. A 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; (S4) Static Screens. A stationary screen designed to remove solids, including non -biodegradable particulate (floatable solids, suspended solids and BOO reduction) from municlpaf 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 ilher 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 dowaterabilhy of sludge by the solubilizing and hydraulizing of the smaller and more highly hydrated sludge particles; (50) Toxic Materials. Those wastes or combinations of wastes. Including cilsease-causing agents which alter discharge and upon exposure, ingestion, Inhalation or assimiration into arty organism, either directly from the environment or indirectly by ingestion through food chains, will cause death, disease; behavioral ahnormalilies, 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 rot limitation: lead, cadmium, chromium, mercury, vanadium, arsenic, zinc, ortho-nitro-chlorobenzene (ONCE), polychlorinated biphenyls (PCBs) and dichlorodiphenyl trichloroethane (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 stone 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 Tale trickling filter is one which is designed to operate at one to four mgd per acre; (60) Trickling Fitter (Packed Tower). A plug flow type of operation In which wastewater flows down through successive layers of media or filtrate material; organic material is removed corrtlnually by the active biological fixed growth In each successive layer. This method may produce 'secondary' quaftty affluent, or may be adapted to produce a nitrifled effluent; (1331) Vacuum Filer, Centrifuges, or Filer Presses- Devices which are deslgnad to remove excess water from either digested or undigested sludge prior to disposal or further treatment.
