A method for treating raw contaminated water includes a housing (21) including a separator element. The separator element includes a membrane which prevents flow of contaminants and allows flow of water such that raw water passing over the membrane passes through the membrane while contaminants are excluded. Contaminants are extracted in a concentration chamber (31) forming a return stream (41), at least part of which is returned to the housing to pass over the separator element again. In one embodiment, gas is injected into the water prior to entering the concentration chamber.

La présente invention concerne un procédé de traitement de l'eau contaminée brute. Ce procédé inclut un carter (21) incluant un élément séparateur. Cet élément séparateur inclut une membrane qui empêche l'écoulement de contaminants et permet l'écoulement d'eau tel que l'eau brute passant au-dessus de la membrane passe au travers de la membrane pendant que les contaminants sont exclus. Les contaminants sont extraits dans une chambre de concentration (31) formant un courant de retour (41) dont au moins une partie est renvoyée dans le carter pour passer de nouveau au-dessus de l'élément séparateur. Selon un mode de réalisation, du gaz est injecté dans l'eau préalablement à l'entrée dans la chambre de concentration.
