Improving the Disinfection Detention Time of a Water Plant Clearwell

Disinfection detention time, one of the key factors in determining compliance with the Surface Water Treatment Rule, was evaluated in this study to determine (1) whether typical water plant basins can be modified with intrabasin baffles to improve detention time and (2) whether model basins can simu...

description Disinfection detention time, one of the key factors in determining compliance with the Surface Water Treatment Rule, was evaluated in this study to determine (1) whether typical water plant basins can be modified with intrabasin baffles to improve detention time and (2) whether model basins can simulate full-scale systems. The results of the work show that both a rectangular and a circular basin can be modeled quite accurately by smallscale basins. Tracer tests showed that T₁₀ detention time can be improved with simple intrabasin baffle walls to approximately 60 percent of theoretical detention time. El tiempo de dilactión de desinfección uno de los factores más importantes en determinar el cumplimiento con la Regla de Tratamiento de Aguas Superficiales, fue evaluado en este estudio para determinar (1) sí los estanques típicos de las plantas de tratamiento de aguas se pueden modificar con secciones retardadoras entre los estanques para mejorar el tiempo de dilación y (2) sí los estanques modelo pueden simular sistemas de escala normal. Los resultados de este trabajo demuestran que tanto un estanque rectangular o circular pueden modelarse con bastante exactitud para estanques de pequeña escala. Pruebas de trazas demuestran que el tiempo de dilación T₁₀ se puede mejorar con simples paredes retrasadoras entre estanques hasta en un 60 porciento del tiempo teórico de dilación.
