Descriptor English:

Water Chlorination

Descriptor Spanish:

Cloración del Agua

Spanish from Spain

Descriptor	cloración del agua
Entry term(s)	cloración (salud ambiental) cloración al punto de quiebra cloración al punto de ruptura
Scope note:	La Ordenanza nº 2.914 de 12 de diciembre de 2011 del Ministerio de Salud, establece en su Art. 34: "Es obligatorio el mantenimiento de, como mínimo, 0,2 mg / L de cloro residual libre o 2 mg / L de cloro residual combinado o de 0,2 mg / L de dióxido de cloro en toda la extensión del sistema de distribución de agua (depósito y red). El objetivo del uso del cloro en sistemas de abastecimiento de agua es la desinfección. Sin embargo, debido a su alto poder oxidante, su aplicación en los procesos de tratamiento ha servido a propósitos diversos como control del sabor y olor, prevención de crecimiento de algas, remoción de hierro y manganeso, remoción de color y control del desarrollo de biopelículas en tuberías. Permite de forma bastante simple, asegurar la inocuidad del agua, desde la producción hasta el momento del uso, lo que resulta en gran beneficio, tanto en pequeños sistemas de comunidades rurales, ribereñas, indígenas, como en grandes ciudades.

Scope note:

The Portaria No. 2,914 of December 12, 2011 of the Ministry of Health, Brazil, establishes in its Article 34: "It is mandatory to maintain a minimum of 0.2 mg / L of free residual chlorine or 2 mg / L of residual chlorine or 0.2 mg / L of chlorine dioxide over the entire length of the water distribution system (reservoir and network) ". The purpose of using chlorine in water supply systems is to disinfect. However, due to its high oxidizing power, its application in the treatment processes has served diverse purposes such as taste and odor control, algae growth prevention, iron and manganese removal, color removal and control of the development of biofilms in pipes. It allows in a very simple way, to assure the innocuity of the water, from the production until the moment of the use, which results in great benefit, in small systems of rural, riverside, indigenous communities, as well as in big cities.
