A00d DEFINITIONS
The following definitions shall apply throughout this Subchapter.
(t) Acttvated Carbon Beds. A physicaVchemical method for reducing soluble organic material from wastewater effluent; The column -type beds used In this
method will have a flow rate varying from two to eight gallons per minute per square loot and may be either upflow or downflow carbon beds. Carbon may or
may not be regenerated on the wastewater treatment plant sire;
(2) Aerated Lagoons. A basin in which all solids are malntalned In suspension and by which bioiogkal oxidation or orgark matter is reduced through artificially
accelerated transfer of oxygen on a flow-through basis;
(3) Aeration. A process of bringing about Intimate contact between air or high purity oxygen In a tlquld by spraying, agitation or dtffusion;(3a) Extended
Aeration. An activaied sludge process utilizing it minimum hydraulic detention time of 16 tours.
(S) Agriculturally managed she. Any site on which a crop is produced, managed, and harvested (Crop Includes grasses, grains, trees, etc.};
(5) Air Stripping. A process by which the ammonlum Ion Is first convened to dissolved ammonia (pH adjustment) with the ammonia then released to the
atmosphere by physical means; or other slmilar processes which remove petroleum products such as ber>?wie, toluene, and xylene;
(6) Catton Regeneration. The regeneration of exhausted carbon by the use of a furnace to provide extremely high temperatures which volatilize anid oxidize the
absorbed Impuritles;
17) Carbonaceous Stage. A stage of wastewater treatment designed to achieve 'secondary' effluent kmlts;
(8) Centrifuge. A mechanical cevice in wNch camr1fugal force Is used to separate solids from Iiqulds or to separate liquids of CrMerent densi.:as;
(9) Chemical Addltlon Systems- The addition of chemlcal(s) to wastewater as an appflcatlon point for purposes of Improving solids removal, pH adfuslmer%
alkalinity control, sir.; the capabltlty to experiment with drfierenl chemicals and different appilratlon points to achieve a spectflc result will be cons{dered one
system; the capabiltly to add chemicals) to dual units will be rated as ori system; capabiitty to add a chemical ata diflereni application points for different
purposes wlil result in the systems being rated as separate syslems;
(10) Chemical Sludge Condhloning. The addition of a chemical compound such as time. lemic chloride, or a pdymer to wet sludge to coalesce the mass prior to
Its application to a dewatering device;
(11) Closad Cycle Systems. Use of holding ponds or holding tanks for containment of wastewater contain€ng Inorganic, rron-loxic materials from nand, gravel,
cashed stone or other s;mitar operations. Such systems shall carry a maximum of two points regardless of pumping facilities or any other appurtenances;
(12) Combined Removal of Carbonaceous BOD and Nitrogenous Removal by Niatfi:atbn- A single cage system required to achieve permit effluent friths on BOD
and ammonia nitrogen within rhe same blo;og€cal reactor,
