Pour que l’eau urbaine soit propre \u00e0 l’irrigation agricole, elle passe par un processus de traitement avanc\u00e9 qui \u00e9limine les contaminants et les agents pathog\u00e8nes. Mais comment garantir sa qualit\u00e9 sanitaire et quelles technologies sont utilis\u00e9es pour la produire ?<\/span><\/p>\n

L’eau r\u00e9g\u00e9n\u00e9r\u00e9e a de nombreuses applications dans divers secteurs. Son utilisation principale se r\u00e9partit en six domaines cl\u00e9s : l’agriculture, l’environnement urbain et l’industrie. Elle est \u00e9galement utilis\u00e9e \u00e0 des fins r\u00e9cr\u00e9atives, ainsi que dans d’autres activit\u00e9s telles que l’aquaculture, l’\u00e9levage et la sylviculture. De plus, l’eau trait\u00e9e joue \u00e9galement un r\u00f4le important dans le domaine environnemental.<\/span><\/p>\n

L’obtention d’une eau urbaine r\u00e9g\u00e9n\u00e9r\u00e9e propre \u00e0 la r\u00e9utilisation n\u00e9cessite des traitements suppl\u00e9mentaires plus avanc\u00e9s afin de r\u00e9duire la charge en contaminants r\u00e9siduels, en mati\u00e8res en suspension et en turbidit\u00e9, ainsi que les micro-organismes pathog\u00e8nes (virus et bact\u00e9ries) afin de garantir la qualit\u00e9 sanitaire de l’eau.<\/span><\/p>\n

Les \u00ab traitements tertiaires \u00bb sont g\u00e9n\u00e9ralement effectu\u00e9s dans les m\u00eames installations que la station d’\u00e9puration, apr\u00e8s le traitement secondaire, dans la section appel\u00e9e station de r\u00e9g\u00e9n\u00e9ration de l’eau (ERA).
\n<\/span><\/p>\n

Le choix des traitements tertiaires d\u00e9pend de deux facteurs :
\n– La ligne de traitement primaire et secondaire existante dans la station d’\u00e9puration.
\n– La qualit\u00e9 requise de l’eau r\u00e9g\u00e9n\u00e9r\u00e9e, afin de s’adapter aux qualit\u00e9s minimales exig\u00e9es pour son utilisation dans la l\u00e9gislation en vigueur.<\/p>\n

Tous ces processus tertiaires de r\u00e9utilisation sont g\u00e9n\u00e9ralement bas\u00e9s sur diff\u00e9rentes combinaisons de technologies, qui varient en termes de complexit\u00e9 et de co\u00fbt d’investissement :<\/p>\n

Physico-chimiques :
\n<\/strong>Coagulation, floculation et d\u00e9cantation
\nFiltration profonde
\nFiltration superficielle
\nFlottation \u00e0 air dissous
\nOxydations avanc\u00e9es<\/p>\n

Membranes de filtration :
\n<\/strong>Microfiltration
\nUltrafiltration
\nNanofiltration
\nOsmose inverse
\n\u00c9lectrodialyse<\/p>\n

D\u00e9sinfection :
\n<\/strong>Rayonnement ultraviolet
\nChlore : principalement hypochlorite de sodium
\nOzone<\/p>\n
