SECTION 2.0:PROJECT DESCRIPTION <br /> the cascading water. The heat removed in the condenser will be discharged to the <br /> atmosphere by heating the air and evaporating some of the cooling water. High efficiency <br /> drift eliminators will reduce drift (the fine mist of water droplets entrained in the warm air <br /> leaving the cooling tower) to 0.0005 percent of the circulating water flow. <br /> 2.1.10 Water Supply and Use <br /> This subsection describes the quantity of water required, the sources of the water supply, <br /> and water treatment requirements. Figure 2.1-5A is a schematic water process flow diagram <br /> and Figure 2.1-5B is the schematic water process flow diagram calculations. Table 2.1-1 <br /> shows water use characteristics keyed to the process flow diagram for (1) the average <br /> annual case (61.2°F dry bulb temperature and 66.8 percent relative humidity) and (2) the <br /> summer maximum case (107.7°F and 18.2 percent relative humidity). Both cases assume <br /> evaporative cooling in operation and duct burning not in operation. The table shows water <br /> usage for the GE 7FA. Complete water balance tables, including additional cases assuming <br /> other temperature, humidity, and operating regimes, are found in Appendix 2A. <br /> TABLE 2.1-1 <br /> Water Use Characteristics Keyed to the Process Flow Diagram(Figure 2.1-5) <br /> Annual Average Summer Max Flow <br /> Figure 2.1-5 61.2°F DB, (Fired) 107.7°F DB, <br /> Identifier Stream Description 66.8% RH 18.2% RH <br /> 1 Influent from Wastewater Treatment Plant 856 1528 <br /> 2 Potable Water Inlet 1 1 <br /> 4 Eye Wash/Safety Shower/Drinking Water 1 1 <br /> 6 CTG Evaporative Cooler Makeup 11 54 <br /> 7 CTG Evaporative Cooler Blowdown 2 9 <br /> 8 CTG Evaporative Cooler Evaporation 9 45 <br /> 9 Micro-Filtration Feed 1008 1784 <br /> 10 Micro-Filtration Blowdown 101 178 <br /> 11 Micro-Filtration Filtrate 907 1606 <br /> 12 Clarifier Feed 846 1518 <br /> 13 1 st Pass RO Feed 103 137 <br /> 14 1st Pass RO Reject 26 34 <br /> 15 1st Pass RO Permeate 77 103 <br /> 16 Cooling Tower Feed 804 1469 <br /> 17 2nd Pass RO Feed 35 42 <br /> 18 2nd Pass RO Reject 3 4 <br /> 19 2nd Pass RO Permeate(EDI Feed) 31 38 <br /> 20 EDI Product 28 34 <br /> 21 EDI Reject 3 4 <br /> 25 Wastewater to Injection Well 103 183 <br /> 26 HRSG Cycle Makeup 28 34 <br /> 2-20 SAC/371322/082340003(LEC_2.0_PROJECT_DESC.DOC) <br />
