Area of ponds will be in range 55-165 acres. <br />(3) Slowdown might first be treated by vapor compression <br />evaporation and then disposed or in much smaller ponds. Cost will <br />be in range 0.3 - 1.5e/106 Stu with pond area not exceeding <br />15 acres. <br /> <br />d) Sour Water Stri;ce~ Wastewater <br />Quantity: Estimated to be about 260 gpm (= 420 acre-ft/yr). <br />Quality: CGD in range 500-1500 mg/l, phenols in range 80-150 mg/l and <br />ammonia in range 25-50 mg/l. <br />Disposal: For dust control within the plant after treatment =y flotaticn <br />and biological oxidation at a cost of SO.80 - 1.20/1000 gals or <br />6 <br />less than 0.2e/lO Btu of synthetic crude. <br />e) Domestic Wastes from Plant <br />Quantitv: 15 gpm (= 24 acre-ft/yrl <br />Ouality: Typical domestic wastewater with a low TDS and a BOD of <br />200-250 mg/l after primary treatment. <br />Disposal: Secondary treatment by packaged activated sludge unit at a <br />6 <br />cost of 51.95/1000 gals ($640/acre-ftl. or O.Ole/lO 3tu. and <br /> <br />then used for revegetation or low quality water needs. <br /> <br />9 <br />
