D004 DEFNITIO S The following definitions shall apply throughout this Subchapter. (1) Activated Carbon Beds. A physicallchemlcal 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 gallon per minute per square toot and may be either upflow or downflow carbon beds. Carbon may or may not be regenerated on the wastewater treatment plant she; (2) Aerated Lagoons. A basin In which all solids are maintained In suspenslon and by which biological oxidation or organic rnatter Is reduced through arlirwJafiy accelerated transfer of oxygen on a flow-through basis; (3) Aerattom A process of bringing about intimate contact between air or high purity oxygen In a liquid by spraying, agitation or diffuslon;(3s) Extended Aeration. An activated sludge process utilizing a m;nlmum hydraulic detention time of 18 hours_ (4) Agrlcuhuraily managed site. Any she on which a crop is produced, managed, and harvested (Crop lnclu los grasses, grains, traas, 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 of a furnace to provide extremely high temperatures which volatilize and oxidize the absorbed lmpuritiss; (7) Carbonaceous Stage. A stage of wastewater treatment designed to'achieva 'secondary' effluent limits; (8) Centrifuge. A mechanical device In which cardrifuga€ force Is used to separate solids from liquids or to separate liquids of cMferent denshfas, (9) Chernkcaf Addition Systems- The adcWon of chemlcal(s) to wastawater at an application point for purposes of improving solids removal, pH adjustment, alkalinity control, etc.; the capability to experiment with d'dforent chemicals and ditfereal application points to achieve a speciflc result will be considered one system; the capability to add chemicals) to dual units will! be rated as one system; capability to add a chomlcat at a different application points for different • oosas will result In the systems being rated as separate systems; Chemlcat Sludge Conciftlorilng. The addhion of a themlca; compound such as rime, ferric chloride, or a polymer to wet sludge to coalesce the mass prior to ppilcatlon to a dewatering device; Closed Cycle Systems_ Use of holding ponds or hok rng tanks for containment or wastewater containing Inorganic, non-toxic materials from sand, gravel, ushed stone or other afmilar operations. Such systems shall carry a maximum of two points regardless or pumping faclfftles or any other appurianances: (12) Combined Removal of Carbonaceous BOD and Nitrogenous Removal by Nhrffication- A single stage system required to achieve permh effluent limits on SOD and ammonia nitrogen within the same biological reactor, (13) Dechlorination. The partial or complete reduction of residual chlorine in a liquid by any chemical or physical process; (14) Denitrification Procass. The conversion of nitrate -nitrogen to Htrogen gas;
