Description
Summary:This report reviews current disinfection practices, the changes made in these practices to meet regulations, and the implications of these changes for operations and finished-water quality. A number of topics are reviewed, including regulations, analytical concerns, trihalomethane control strategies, and adverse effects of disinfection. These topics reflect the complexity of current disinfection issues and the changing nature of drinking water regulations. This report also includes recent water utility survey data that provide a look at current disinfection practices and operations compared with practices in the late 1970s. Este informe estudia los diferentes sistemas de desinfección, los cambios realizados en estos sistemas para ajustarse a las reglas, y las implicaciones de estos cambios en las operaciones y la calidad del agua terminada. Se revisa una serie de tópicos, incluyendo las reglas, preocupaciones analíticas, estrategias en la limitación de trihalometano, y los efectos adversos de la desinfección. Este informe incluye también un estudio reciente de acueductos que dan un vistazo actual a los diferentes sistemas y operaciones comparadas con los sistemas usados a finales de los años 70.
