The following definitions shelf apply throughout this Subchapter.
(1) Activated Carbon Bads. A physical/chemical method for reducing soluble organic material from wastewalor affluent; The oofumn-type beds used in this
method will have a flow rate varying from two 10 aighl gallons par minute per square foot and may be either upl€ow or downtlow carbon beds. Carbon may or
may no( be regenerated on the wastewaler trealmarA plant she;
(2) Aerated Lagoons. A basin in which all solids are rlafnlained in suspension and by which Coiogical oxidation or organic matter is reduced through anificiatly
accelerated transfer of oxygen on a slow -Through basis;
(3) Aeration, A process of bringing about Intimate contact between air or high purity oxygen In a I!quid by spraying, agitation or di%sion;(3a) Exlanded
Aeration, An aclivaWd sludge process utilizing a minimum hydraulic detention time of 18 hours,
(4) Agriculturally managed site. Any silo on which a crop is produced, managed, and harvested )Crop Includes gras.sas, grains, uses, etc.);
(5) Air Stripping. A process by which the ammoniurn ion Is first corwarted to dissolved amrn�nia (pH adjustment) with the ammonia than released to the
atmosphere by physical means; or olhar similar processes which remove petroleum products such as benzene, toluene, and xylene;
(6) Carbon Reganeralton The regeneration of exhausted carbon by the use of a furnace to provide extremely high lemperatures which volatilize and oxidize the
absorbed impurities;
(7) Carbonaceous Stage. A st;;ge of wastewater treatment designed to achieve 'secondary' affluent 11mits;
(8) Centrifuge. A machanical de-ri--i3 In which cenlitugal force is used to separate solids from liqulds or to saparale liquids of different densrlas;
(9) Chemical Addition Systems- The addhlon of chernlcaf(s) to waslawaler at an application point for purposes of Improving solids removal, pH_ad)usiment,
tlkalinhy control, etc.; the capability to experiment with different chemicals and different application points 10 achieve a specific result will be considered one
,fslem; the capabit4y to add chamical(s) to dual units will be rated as one syslam; capability to add a chemical at a different application points for different
Ourposes will result In the systems being rated as separate systems;
(10) Chemical Sludge Condr'on,ng. The addition of a chemical compound such as lime, ferric chloride, or a polymer to wel sludge to malesce If1e mass prior to
Pis application to a dewatering device;
(11) Ciosed Cycle Systems- Use of holding ponds or, holding tanks for contafnmenl of wastewater conta!ning inorganic, non-loxic materials from sand, gravel,
crushed stone or other similar eeeration5. Such systems shall carry a maxlrnum of Ivry points regardless of pumping tacililies or any other appurlsna toss;
(12) Combined Removal of Carbonaceous BOD and Nitrogamus Removal by NhMicalton- A sirgie slags system rsquinad to achieve permit effluent !im;.s on EOD
and ammonia n trcgen within 171e same biological reactor,
(13) Dechlorirailon. The pa-i;e or complela redic ion of residual chlorine in a I,quid by any chernical or physical process;
(14) Denhrhicat;on Proses, The eonvarslon of nhralo-nilrogan to nitrogen gas;
