Abstract

Procédé biologique de dessalement d’une eau à traiter ayant une concentration en chlorure de sodium comprise entre 20 et 80 g/L, ledit procédé comprenant :a) la fourniture initiale de bactéries halotolérantes dessalantes non photosynthétiques ;b) la mise en œuvre de cycles de dessalement successifs, chaque cycle de dessalement comprenant les étapes suivantes :i) une étape d’accumulation par mise en contact de l’eau à traiter avec lesdites bactéries halotolérantes dessalantes non photosynthétiques, afin de produire un effluent appauvri en chlorure de sodium et des bactéries chargées en chlorure de sodium ;ii) une étape de récupération de l’effluent appauvri en chlorure de sodium ;iii) une étape de régénération par mise en contact desdites bactéries chargées en chlorure de sodium avec une eau de lavage, afin de régénérer, au moins en partie, lesdites bactéries chargées en chlorure de sodium par relargage des sels accumulés dans l’eau de lavage;iv) une étape de recyclage par mise en contact desdites bactéries régénérées, au moins en partie, avec l’eau à traiter afin de réaliser le cycle de dessalement suivant.
