dc.description.abstract | Cuando se construyó la depuradora de Lake George en 1939, se describió como una depuradora completa. Esto se debía a que el efluente tratado se vertía en lechos naturales de filtración de arena que tenían "al menos 25 pies de profundidad". En los últimos años se ha observado un aumento de la concentración de nutrientes en el extremo sur del lago George, cerca de Lake George Village. El objetivo de este estudio era determinar si el efluente de la planta de tratamiento tenía algún efecto en este aumento de la concentración de nutrientes. El plan original era localizar el nivel freático cerca de la planta de tratamiento y, mediante el uso de un colorante, rastrear el flujo a través del suelo. Se descubrió que la capa freática estaba a más de 1,5 metros de profundidad y que los lechos de arena naturales también tenían más de 1,5 metros de profundidad. -Debido a la escasez de fondos para la perforación de pozos, se revisó el alcance del proyecto. El nuevo objetivo era determinar la eficacia de eliminación de los lechos de arena con respecto a los coliformes, la DBO, los cloruros y los compuestos de nitrógeno y fósforo. Se comprobó que cuando se dosificaban los lechos, dejaban de estar saturados a los 15 pies. Se comprobó que tres metros de arena eliminaban los coliformes en un 99% y la DBO en un 96%. Sin embargo, los nitratos, fosfatos y cloruros permanecieron en concentraciones significativas después de la filtración a través de 10 pies de arena. | spa |
dc.description.abstract | When the Lake George Sewage Treatment Plant was constructed in 1939 it was described as a complete treatment plant. This was because the treated effluent was discharged onto natural sand seepage beds which were "at least 25 feet deep". In recent years, an increase in nutrient concentration has been noted at the south end of Lake George near Lake George Village. The object of this study was to determine if the treatment plant effluent had any effect on this increased nutrient concentration. The original plan was to locate the ground-water table near the treatment plant and by use of a dye. trace the flow through the ground. It was found that te ground-water table was deeper than 56 feet and the natural sand beds were also greater than 56 feet in depth. ·Due to limited funds for well drilling exploration,the project scope was revised. The new objective was to determine the removal efficiency of the sand beds with respect to coliforms, BOD, chlorides, and the nitrogen and phosphorus compounds. It was found that when beds were dosed, they were no longer saturated at 15 feet. Ten feet of sand was found to remove coliforms by 99% and BOD by 96%. However, nitrates, phosphates, and chlorides remained in significant concentrations after filtration through 10 feet of sand. | eng |
