Honorable Chairman and <br />Board of County Commissioners <br />9/16/91 <br />Page 17 <br />RECEIVING FACILITY <br />Sludge, septage, and grease wastes are introduced to treatment at a <br />controlled rate rather than being received in "slug" Toads. The function of <br />the receiving facility is to accept these wastes at highly variable dumping <br />rates and to discharge them to the treatment process at a steady rate. No <br />biological treatment of the wastes is provided in this receiving facility. <br />The receiving facility is designed to minimize the potential for odors <br />normally generated during dumping. <br />County -contracted haulers transport septage from County owned and operated <br />facilities to the Facility in their vehicles and discharge the sludge via a <br />quick -connect coupling directly to a receiving manhole. Private haulers <br />transporting septage and grease discharge their wastes via the same method. <br />The dumping area is sloped toward the receiving manhole to provide collection <br />and control of any spillage. The wastes flow through a bar screen into a <br />holding tank with mechanical mixers to keep the contents in suspension. <br />A bar screen is a necessary unit process for a receiving facility. A manual <br />bar screen has been selected for Indian River County based on the design of <br />the receiving facility to operate in a batch mode. An operator will be <br />present when sludge, septage, or grease loads are discharged to the receiving <br />facility. Therefore, the operator will be available to clean the bar screen <br />during this operation. <br />The septage holding tank is divided into two sections and provides 24-hour <br />storage capacity in each section for the incoming septage. Having two <br />sections in the tank enables a combination of isolation and flow control into <br />M.VRB2/5 <br />
