WASTEWATER AND ITS CHARACTERISTICS:
BOD (Denoting Biochemical Oxygen Demand): The quantity of oxygen utilized in the biochemical oxidation of organic matter under standard laboratory procedure in five (5) days at twenty degrees Celsius (20°C), expressed in milligrams per liter.
Effluent Criteria: As defined in any applicable "NPDES permit".
Floatable Oil: Oil, fat or grease in a physical state such that it will separate by gravity from wastewater by treatment in an approved pretreatment facility. A wastewater shall be considered free of floatable fat if it is properly pretreated, and the wastewater does not interfere with the collection system.
Garbage: Solid wastes from the domestic and commercial preparation, cooking and dispensing of food and from the handling, storage and sale of food.
Industrial Waste: Any solid, liquid or gaseous substance discharged, permitted to flow or escaping from any industrial, manufacturing, commercial or business establishment or process, or from the development, recovery or processing of any natural resource as distinct from sanitary sewage.
Major Contributing Industry: An industrial user of the publicly owned treatment works that:
(A) Has a flow of fifty thousand (50,000) gallons or more per average workday; or
(B) Has a flow greater than ten percent (10%) of the flow carried by the municipal system receiving the waste; or
(C) Has in its waste a toxic pollutant in toxic amounts as defined in standards issued under section 307(a) of the federal act; or
(D) Is found by the permit issuing authority, in connection with the issuance of the NPDES permit to the publicly owned treatment works receiving the waste, to have significant impact, either singly or in combination with other contributing industries, on that treatment works or upon the quality of effluent from that treatment works.
Milligrams Per Liter: A unit of the concentration of water or wastewater constituent. It is 0.001 g of the constituent in one thousand milligrams (1,000 mg) of water. It has replaced the unit formerly used commonly, parts per million, to which it is approximately equivalent, in reporting the results of water and wastewater analysis.
ppm: Parts per million by weight.
pH: The logarithm (base 10) of the reciprocal of the hydrogen ion concentration expressed by one of the procedures outlined in the IEPA division of laboratories manual of laboratory methods.
Properly Shredded Garbage: The wastes from the preparation, cooking and dispensing of food that have been shredded to such degree that all particles will be carried freely under the flow conditions normally prevailing in public sewers.
Sewage: Is used interchangeably with "wastewater".
Slug: Any discharge of water, sewage or industrial waste which, in concentration of any given constituent or in quantity of flow, exceeds for any period of duration longer than fifteen (15) minutes more than five (5) times the average twenty four (24) hour concentration of flows during normal operation.
Suspended Solids (SS): Solids that either float on the surface of, or are in suspension in water, sewage or industrial waste, and which are removable by a laboratory filtration device. Quantitative determination of suspended solids shall be made in accordance with procedures set forth in the IEPA division of laboratories manual of laboratory methods.
