Major Treatment Elements: "conventional" complete mix <br />activated sludge with screen, flow measurement, final <br />clarifier, chlorination, sludge drying beds and by-pass <br /> <br />B. Location <br /> <br />1. Address: southeast edge of town <br /> <br />2. Map co-ords: NW ~ of Sec. 10, T28S, R66W, 6th PM <br /> <br />C. Construction History: The plant was constructed in 1966. <br /> <br />D. "Hardware": <br /> <br />lift station: (2) Fairbanks-Morse pumps, 500 gpm @ 8 ft. <br />3 hp Westinghouse <br />(2) Yeoman, 15 hp aerators, 7 ft. cones <br />clarifier, Yeoman, 39 ft. diameter <br />chlorinator, Fisher-Porter <br />(2) 7.5 hp sludge pumps <br /> <br />IV. PLANT OPERATION <br /> <br />. <br /> <br />. <br /> <br />. <br /> <br />A. Process Variables: sludge return rate and sludge wasting <br />rate <br /> <br />B. Residuals Handling: The aerators need cleaning on a twice <br />per week basis due to the buildup of rags and other debris <br />on the impeller. The bar screen is cleaned twice per day. <br /> <br />C. Plant Operation <br /> <br />1.
