The following definitions shall apply throughout this Subdhapler.
(1) Activated Carbon Beds. A physicat/chemical 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 ragenerated on the wastewater treatment plant she;
(2) Aerated Lagoons. A basin In which all solids are maintained in suspension and by which bk4ogkal oxidation or panic matter Is reduced through artificially
accelerated transfer of oxygen on a flow -through basis;
(3) Aeration A process o1 bringing about Intimate contact between air or high purity oxygen In a liquid by spraying, aghatlon or dffuslon;(3a) Extended
Aeration. An activated sludge process utilizing a minimum hydraulic detentions time of 18 hours.
(4) 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 ammonium ion Is first converted to dissolved ammonia (pH adjustment) with the ammonia then released to the
atmosphere by physical means; or other similar processes which remove petroleum products such as benzene, toluene, and xylene;
(6) Carbon Regeneration. The regeneration of exhausted carbon by the use 01 a furnace to provide extremely high temperatures which votatillze and ox)dlze the
absorbed Impwrides;
(7) Carbonaceous Stage. A stage of wastewater treatment designed to achieve lsecondaryr effluent limits:
(8) Centrifuge. A mechanical device In which centrifugal force Is used to separate solids from liquids or to separate liquids of dffereal densrlas;
(9) Chemical Addition Systems- The addhlon of chemkal(s) to wastewater at an application point for purposes of Improving solids removal, pH adjustment,
alkalinity control, etc.; the capability to experiment with ddlorent chemicals and different application points to adtileve a specific resuh will be considered one
system; the capability to add chemkal(s) to dual units will be rated as one "am, capability to add a chemical at a different application points for different
purposes will resuh in the systems being rated as separate systems;
(10) Chemical Sludge Condhtoning. The addition of a chemical compound such as time, ferric chloride, or a polymer to wet sludge to coalesce the mass prior to
Its application to a dewatering device;
(11) Closed Cycie Systems. Use of holding ponds or holding tanks for corrtalnmerrt of wastewater containing Inorgank, non -toxic materials from sand, gravel,
crushed stone or other similar operations. Such systems shall carry a maximum of two points regardless of pumping tact€hies or any other appurtenances;
(12) Combined Removal of Carbonaceous DOD and Nitrogenous Removal by Nitrification- A single stage system required to achieve permit effluent I'sml:s on DOD
and ammonia nitrogen within the same biological reactor,
(13) Dechiorinatlon The partial or complete reduction of residual chlorine in a liquid by any Chemical or physical process;
(14) Derihrificailon Process. The conversion of nhraie-nitrogen to nitrogen gas;
